ANSWER:
60°
EXPLAINATION:
= 2r + θ/360°× 2 x 227 x 21
64 = 2 x 21 + θ/360° x 2 x 22/7 x 21
64 = 42 + θ/360° x 44 x 3
64 - 42 = θ/360° x 11 x 3
22 = 33θ/90
θ=22×30/11
= 60°
Answer:
5
Step-by-step explanation:
Answer:
b=112°
Step-by-step explanation:
two complementary angles
b=180°-68°=112°
sum of 2 angles is
x= 35°+25°=60°
Inverse variation means
When the value of x increases the value of y decreases.
When the value of x decreases the value of y increases.
So for an inverse variation we have the expression

or

The expression which represents this condition is

Hence option b) or the second option is the right answer.
