In △abc, m∠a=15°, a=9, and b=10. find c to the nearest tenth.

In △ABC, m∠A=15°, a=9, and b=10

We apply sine law

0.287576716 = sin(b)

b= 16.7129 degree

angle A= 15 degree, angle B = 16.71 degree

So angle C = 148.29

c=

c= 18.28

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
