Which angles are acute?
А в
H
Check all that apply.

The answer is A and D.

Step-by-step explanation:

Acute angles are angles that are less than 90°.

0° < θ < 90°.

So by looking at the diagram, any angles that are smaller than a L-shaped(90°) are all acute angle.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

the answer would be c:   ax + b = ax + c
