What do squares, rectangles, and right triangles have in common? They all contain at least one right angle!
What shape has at least one right angle?
rectangle
A rectangle is a four-sided shape where every angle is a right angle (90°). Also, the opposite sides are parallel and of equal length.
The shapes which contain at least one right angle from the given shapes are the first and third figures.
Given are four shapes.
It is required to find the shape with at least one right angle.
Now, right angles can be defined as the angle whose measure is exactly 90 degrees.
Anything measure of angle which is less than or greater than 90 degrees is not a right angle.
Consider the first figure.
There are 2 right angles marked in squared shape inside the shape in the right part.
So, the first figure contains the right angle.
In the second figure, all angle measures are 108 degrees. So none is a right angle.
In the third figure, all the angles are right angles since all are marked as squares.
In the last figure, the angle measures are only 73° and 107°. So, this is not right angles.
Hence, the options are first and third figures.

The sum of the lengths of any two sides is greater than the third side, then the given sides will form a triangle.
Apply the theorem statement for the given numbers 10, 7 and 13. Do these numbers form a triangle? Explain
Answer:
Yes, These numbers 10, 7, and 13 can form a triangle
Step-by-step explanation:
The sum of any two sides of a triangle is greater than the third sideLet us use this theorem to solve the question
∵ The numbers are 10, 7, 13
∵ 10 + 7 = 17
∵ 17 > 13
∴ The sum of 10 and 7 is greater than the 3rd number 13
∵ 10 + 13 = 23
∵ 23 > 7
∴ The sum of 10 and 13 is greater than the 3rd number 7
∵ 7 + 13 = 20
∵ 20 > 10
∴ The sum of 7 and 13 is greater than the 3rd number 10
∵ The sum of every two numbers is greater than the 3rd number
→ By using the theorem above
∴ The numbers 10, 7, and 13 can form a triangle

solve for x
Answer:
x = 6
Step-by-step explanation:
4x + 5 = 6x - 7 subtract 4x from both sides
5 = 2x - 7 now add 7 to both sides
12 = 2x finally divide both sides by 2
