1st question : 16,22. 14,20. 12,18
Answer:
15.28
Step-by-step explanation:
first we divide 96 by 3.14 to get the diameter
96÷3.14=30.57
now we have the diameter we divide by two to get the radius
30.57÷2=15.28
15.28 is your radius
Answer:
8, 9
Step-by-step explanation:
We know that
if sin A=cos B
then
angle A and angle B are complementary angles
so
A+B=90 degrees
in this problem
(x+34)+(2x+20)=90-------> 3x+54=90----> 3x=90-54-----> x=36/3----> x=12°
the answer is
the value of x is 12 degrees
