Answer the questions in the image. i’m desperate.

Step-by-step explanation:

3.) Isosceles because: (of a triangle) having two sides of equal length.

4.) Equilateral because: having all its sides of the same length.

5.) Use the Pythagorean Theorem formula a^2 + b^2 = c^2

a.) 59^2 + 61^2 = 62^2

3481 + 3721 = 3844

7202 = 3844

Acute because 7202 > 3844

b.) 30^2 + 25^2 = 125^2

900 + 625 = 15625

1525 = 15625

Obtuse because 1525 < 15625

c.) 56^2 + 72^2 = 52^2

3136 + 5184 = 2704

8320 = 2704

Acute because 8320 > 2704

d.) 90^2 + 45^2 = 45^2

8100 + 2025 = 2025

10125 = 2025

Obtuse because 10125 > 2025

no
