Answer:
Angle 1 and angle 3 are vertical angles.
Step-by-step explanation:
They are diagonal from each other causing it to be vertical angles and equal.
Given:
.
To find:
The value of x.
Solution:
In triangles ABC and ADE,
(Right angles)
(Common angles)
(AA property of similarity)
We know that the corresponding sides of similar triangles are proportional. So,




On cross multiplication, we get



Therefore, the value of x is
units.
Answer is a right triangle. The angles of a triangle must add to 180 degrees.
You have two 45 degree angles
45 + 45= 90
Now you need 1 more angle to equal 180
180- 90= 90
A right angle is 90 degrees. A right triangle has one right angle and two acute.
The answer is D: 1,512 cubic inches. You can get this by multiplying the number on the first cube together, multiplying the numbers on the second cube together, and then adding those two numbers together.
