Find

(a) the value of q in radians

(b) the area of the shaded region in cm²

(a) 1.18

(b) 99.71

Step-by-step explanation:

to know the value of q in degrees we can use cosine of q

now to radians

the formula is

with x the degrees

so the measure of angle q is 1.18 radians

so now for part b

with being the central angle in radians

for degrees is the following

so we have

cm^2

17.08

correct me if i am wrong.

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
