<u>y = 25</u>
Step-by-step explanation:
<u>=> 115 = y + 90 {exterior angle of triangle is equal to the sum of its opposite two interior angles}</u>
<u>=> 115 = y + 90 </u>
<u>=> 115-90 =y</u>
<u>=> 115 = y + 90</u>
<u>=> 115-90 =</u><u>y</u>
<u>=> y = 25</u>
Answer:r
=8 in
Step-by-step explanation:
A=π⋅r2 64π=π⋅r2
Divide by pi on both sides
64=r2
r=8 and−8 but since distance can't be negative, the answer is just 8
Answer:
15/4
Step-by-step explanation:
F(g(x)= x+4
f(x+4)= 5(x+4)-9
=5x+20-9
=5x+11
g(f(x)= 5x-9
g(5x-9)=5x-9+4
=5x-5
