Can someone help me with this geometry question pls???

i think it's A.) 5.5

Step-by-step explanation:

A right triangle has 90°

Given: 15 and 20

15 + 20 = 35

90 - 35 = 55

55 is the missing angle

Round to the nearest tenth: 55 ÷ 10 = 5.5

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
