Answer:
115 3/4
Step-by-step explanation:
Because d=1/2. 1/2*1/2=1/4
C=5 so, C^3=5x5x5
C=125
Next, b=9
Then, you put everything together.
1/4+125-9=125 1/4-9
115 3/4
115 3/4+9 1/4
5? Did you mean to insert a picture
11/16 it’s reduced, thank me later!
6 acts as the base. 15 acts as the height, because it extends from the base to meet vertex opposite the base at a 90° angle.
General formula for triangle area
a = 1/2 × b × h
plug in the numbers
a = 1/2 × 6 × 15
a = 90/2
a = 45
The area of the triangle is 45 units²
the answer is the first choice
