The three inside angles (A, B and C) of a right angled triangle are in the ratio 7:18:11

The smallest angle is 35°

Work out out angles a,b and ,

Answers

Answer 1

Answer:

Angle A =35 degrees, Angle B = 90 degrees, and Angle C = 55 degrees

Step-by-step explanation:

So all the angles added up would be 180. Let's use the variable x. The angles would be 7x, 18x, and 11x.

The smallest angle is 35, and 7x is the smallest out of all them since x has to be positive.

7x = 35

x = 5

Then substitute x into each angle.

They would be 35 degrees, 90 degrees, and 55 degrees

Write an equation of the line that
passes through (-1,2) with a slope of 4

Answers

Step-by-step explanation:

Hey there!

Given;

The points is; (-1 , 2) and slope is 4.

Note: Use one-point formula.

[tex](y - y1) = m(x - x1)[/tex]

~ Put all values.

[tex](y - 2) = 4(x + 1)[/tex]

~ Simplify it.

[tex](y - 2) = 4x + 4[/tex]

[tex]4x - y + 6 = 0[/tex]

Therefore, the required equation is; 4x-y+6=0.

In a​ triangle, the measures of the three angles are​ x, x + 12 ​, and x-9. What is the measure of each​ angle?

Answers

x + x + 12 + x - 9 = 180
3x = 180 - 12 + 9
3x = 168 + 9
3x = 177
x = 59 degrees

Angle 1 = 59 degrees
Angle 2 = 59 + 12 = 71 degrees
Angle 3 = 59 - 9 = 50 degrees

Answer:

x+(x+12)+(x-9)=180

3x+12-9=180

3x=180-3

3x=177

x=177/3

x=59

Each angle is 59°, 71° and 500°

What is 3/11 of 22/39?

Answers

Answer:

0.1538

Step-by-step explanation:

first convert 3/11 into a percentage

3÷11=0.272727272727273

0.272727272727273 × 100

27.272727272727/100

27.272727272727%

≈27.27%

27.27% of 22/39

change 22/39 into a decimal

22÷39=0.5641025641》0.564

27.27% of 0.564

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 27.27% * 0.564

Converting percent to decimal:

p = 27.27%/100 = 0.2727

Y = 0.2727 * 0.564

Y = 0.1538

Answer:

Find the gradient of the line segment between the points (7,2) and (10,-5).
Give your answer in its simplest form.​

Answers

Given:

Two end points of a line segment are (7,2) and (10,-5).

To find:

The gradient of the given line segment.

Solution:

We know that, gradient of a line segment is the slope of that line segment.

The end points of the line segment are (7,2) and (10,-5), so slope or gradient of the line segment is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{-5-2}{10-7}[/tex]

[tex]m=\dfrac{-7}{3}[/tex]

Therefore, the gradient of the given line segment is [tex]\dfrac{-7}{3}[/tex].

Which graph represents an exponential function?

Answers

Answer:

A simple exponential function to graph is y=2x . Notice that the graph has the x -axis as an asymptote on the left, and increases very fast on the right. Changing the base changes the shape of the graph. Replacing x with −x reflects the graph across the y -axis; replacing y with −y reflects it across the x -axis.

Find the solutions of the quadratic equation -9c² +2 +3 = 0.

Answers

Given that,

An equation : -9c² +2c +3 = 0

To find,

Find the value of x.

Solution,

We have, -9c² +2c +3 = 0

We can solve it using the formula as follows :

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Here, a = -9, b = 2 and c =3

Put the values,

[tex]c=\dfrac{-2\pm \sqrt{(2)^2-4(-9)(3)}}{2(-9)}\\\\c=\dfrac{-2+\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}, \dfrac{-2-\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}\\\\c=-0.47, 0.69[/tex]

So, the solution are -0.47 and 0.69.

Suman bought a tea pack of 0.345kg. From that, 40g of tea was taken. What

is the amount of tea left with her?Pls answer fast

Answers

Answer:

The remaining tea = 0.305 kg

Step-by-step explanation:

The mass of Tea pack = 0.345 kg

The mass of tea taken = 40 g

as

40 g = 0.04 kg

Therefore, all we need is to subtract 0.04 kg from 0.345 kg to determine the tea left:

i.e.

Remaining Tea left = Total tea - Tea taken

                                = 0.345 - 0.04

                                = 0.305 kg

Therefore, the remaining tea = 0.305 kg
