Answer:
D
Step-by-step explanation:
It has to be angle angle angle because angle angle angle cannot be used to prove that any triangles are congruent
To find the value of x, we need to use Pythagorean Theorum.
The equation for Pythagorean Theorum is a^2 + b^2 = c^2.
C^2 is our hypotenuse, or the side that's across from the right angle.
13 is our hypotenuse, and 12 is b.
Since our numbers are not squared, let's square them.
13 x 13 = 169
12 x 12 = 144.
Our equation now is a^2 + 144 = 169
To find a^2, we need to subtract b^2 from c^2.
Subtract 144 from 169.
169 - 144 = 25.
a^2 = 25
Square root both sides.
a = 5.
x = 5.

Answer:
The lengths that represent the legs of tri ABC are AC and BC
Step-by-step explanation:
AB is the hypotenuse as it is the side opposite to 90°
Answer:
68 cm²
Step-by-step explanation:
I don't see what you mean for each figure but here goes nothing!
We can split the figure in 2 rectangles
We find the first rectangle by doing 4 x 12 = 48 cm²
The second rectangle would be 5 x 4 = 20 cm²
Therfore we add them up into 20 + 48 = 68 cm²
Hope This Helps!
