Answers
Answer:
a and c
Step-by-step explanation:
∠ 1 = 60° ( vertical angle )
The sum of the 3 angles in a triangle = 180°, thus
∠ 2 = 180° - (60 + 70)° = 180° - 130° = 50° → a
(7)
∠ 3 = 180° - (60 + 40)° = 180° - 100° = 80°
∠ 3 and ∠ 4 are adjacent angles and supplementary , thus
∠ 4 = 180° - ∠ 3 = 180° - 80° = 100° → c

image In the figure, is the segment bisector of AB such that AP = 15x – 11 and PB = 9x + 25. Find the value of x. Question 5 options: A) 6 B) 5 C) 7∕3 D) 10
Answers
Answer:
[tex]x =6[/tex]
Step-by-step explanation:
Given
Bisected Sector AB;
AP = 15x - 11
PB = 9x + 25
Required
Find x
When a sector is bisected, it means the sector is divided equally into two;
Hence [tex]AP = PB[/tex]
This gives
[tex]15x - 11 = 9x + 25[/tex]
Add 11 to both sides
[tex]15x - 11 + 11 = 9x + 25 + 11[/tex]
[tex]15x = 9x + 25 + 11[/tex]
[tex]15x = 9x + 36[/tex]
Subtract 9x from both sides
[tex]15x - 9x = 9x + 36 - 9x[/tex]
[tex]15x - 9x = 9x - 9x + 36[/tex]
[tex]6x = 36[/tex]
Divide through by 6
[tex]\frac{6x}{6} = \frac{36}{6}[/tex]
[tex]x = \frac{36}{6}[/tex]
[tex]x =6[/tex]
Hence, the value of x is 6
Answer:
x=6
Step-by-step explanation:
15x-11=9x+25
15x-9x=25+11
6x=36
x=6

Find the counterexample to one of the following statements
1). A triangle cannot have an angle that is greater than 90º .
2). The product of two positive numbers is always greater than their sum.
Answers
Answer:
1) You know that the addition of all interior angles of a triangle always should add up to 180°
Then, for example, we can construct a triangle with angles
100°, 40°, 40° such that
100° + 40° + 40° = 180°
So we have an example of a triangle that has one angle greater than 90°.
2) Suppose that we have the positive numbers 0.5 and 1.
The product is: P = 0.5*1 = 0.5
the sum is: S = 0.5 + 1 = 1.5
The sum is greater than the product.

Answer:
A rectangular prism measuring 4 cm by 5 cm by 8 cm and a rectangular pyramid with the dimensions of 2 cm by 4 cm by 8 cm ⇒ 1st answer
Step-by-step explanation:
* Lets explain how to solve the problem
- The container is shaped a rectangular prism
- Its base is a rectangle of dimensions 4 cm by 8 cm
- Its height is 5 cm
- The lid of the container is shaped a rectangular pyramid
- Its base is a rectangle with the same dimension of the base of the
container 4 cm by 8 cm
- Its height is 2 cm
* Lets solve the problem
∵ The container is shaped rectangular prism
∵ The base of the container is a rectangle with dimensions 4 cm
by 8 cm
∵ The height of the container is 5 cm
∵ The led of the container is shaped a rectangular pyramid
∵ The base of the lid of the container is a rectangle with dimensions
4 cm by 8 cm
∵ The height of the lid is 2
∴ A rectangular prism measuring 4 cm by 5 cm by 8 cm and a
rectangular pyramid with the dimensions of 2 cm by 4 cm by
8 cm is the correctly describes the dimensions of the figures
that make up the container and its lid

The ratio of the number of roses to the number of daises in a garden is 4:3. If there are 42 daises in the garden, how many roses are in the garden?
Answers
Answer:
56
Step-by-step explanation:
The 3 part of the ratio represents daisies.
Divide the number of daisies by 3 to find the value of one part of the ratio.
42 ÷ 3 = 14 ← value of 1 part of the ratio, thus
4 parts = 4 × 14 = 56 ← number of roses
