Based on the angle addition postulate, the measure of angle 1 is calculated as: 88°.
What is the Angle Addition Postulate?The angle addition postulate states hat the sum of two smaller angles is always the measure of a bigger angle from which the smaller angles are formed from.
Given:
Measure of angle 2 = 45°
Measure of angle XWY = 133°
Therefore:
Measure of angle 1 + 45 = 133 [angle addition postulate]
Subtract 45 from each side of the equation
Measure of angle 1 + 45 - 45 = 133 - 45
Measure of angle 1 = 88°
Therefore, based on the angle addition postulate, the measure of angle 1 is calculated as: 88°.

Answers
Answer:
A. It can be expressed as a non repeating, non terminating decimal.
Step-by-step explanation:
Irrational numbers are numbers with a decimal that goes on forever.
The decimal also never repeats, for the entirety that it goes on.
Since the solution is an irrational number, this means that the solution can be expressed as a non-repeating and non-terminating decimal.
So, A is the correct answer.

Hope this helps plz hit the crown ;D
12 boys should be enrolled to make the ratio into 1 : 1
What is a ratio?'A ratio is a mathematical expression written in the form of a : b, where a and b are any integers. It expresses a fraction.'
According to the given problem,
Given ratio = 4:7
Total number of students = 44
Let the unknown integer multiplier be x,
⇒ 4x + 7x = 44
⇒ 11x = 44
⇒ x = 4
Number of boys = 4 × 4
= 16
Number of girls = 4 × 7
= 28
Therefore number of boys to be enrolled = 28 - 16
= 12
Hence, we can conclude, 12 boys should be enrolled with the already enrolled 16 so as to make boys : girls as 1 : 1.

WILL GIVE BRAINLIEST! Find the equation of a line that passes through (-5,-2) and the intersection of the lines x+3y=0 and 4x-4y-13=0
Answers
Answer:
y + 2 = -0.069(x-+5)
Step-by-step explanation:
SInce the two lines intersects, we will equate it
Multiply x + 3y = 0 by 4;
4x + 12y = 0
4x-4y-13 = 0,
Subtracts both
12y +4y + 13 = 0
16y = 13
y = 13/16
get x;
x + 3(13/16) = 0
x = -39/16
The point of intersection is (0.8, -2.4) and (-5,-2)
Get the equation;
m = y2-y1/x2-x1
m = -2+2.4/-5-0.8
m = 0.4/-5.8
m = -0.069
Get the equation;
y - y0 = m(x-x0)
y - (-2)= -0.069(x-(-5))
y + 2 = -0.069(x-+5)

Answers
Answer:
Milk - 3 cups
Eggs - 2
Self-Raising Flour - 4 cups
Caster Sugar - 2/3 cup
Melted Butter - 50g
Step-by-step explanation:
The question asks for the quantity of each ingredient needed to make 24 pancakes. The recipe we are given makes 12 pancakes.
To figure out our proportions, we can divide the number of pancakes we need to make by how many the recipe makes.
24/12 = 2
This tells us that we will need to double the quantity of each ingredient in the recipe to make 24 pancakes.
1.5 · 2 = 3 cups of milk
1 · 2 = 2 eggs
2 · 2 = 4 cups of self-raising flour
1/3 · 2 = 2/3 cup of caster sugar
25 · 2 = 50g of melted butter

Compare the square root of one hundred forty and one hundred three ninths using <, >, or =.
Answers
The square root of one hundred forty > the square root of one hundred three ninths
In this question, we need to compare the square root of one hundred forty and the square root of one hundred three ninths.
We write the square root of one hundred forty as,
√(140)
The value of the square root of one hundred forty is,
√(140) = 11.8 ..............(1)
We write the square root of one hundred three ninths as,
√(11.44)
The value of the square root of one hundred three ninths is,
√(11.44) = 3.4 ...................(2)
From (1) and (2),
11.8 > 3.4
i.e., the square root of one hundred forty is greater than the square root of one hundred three ninths
Therefore, the square root of one hundred forty > the square root of one hundred three ninths

Answers
Answer:
When x=6 in the domain, then y=26 is the corresponding element in the range of the function f(x)=7x-16.
Step-by-step explanation:
Given the expression
[tex]f(x)=7x-16[/tex]
Given that x=6 is an element in the domain of f(x).
Substituting x=6 in the expression to find the corresponding element in the range.
[tex]f(6)=7(6)-16[/tex]
[tex]= 42-16[/tex]
[tex]= 26[/tex]
Thus, the corresponding element in the range is: y=26
Therefore, we conclude that:
When x=6 in the domain, then y=26 is the corresponding element in the range of the function f(x)=7x-16.
