Question

8.2.AP-7

B
Find the measure of side c.
a = 26 m
C
C=
m (Round the answer to the nearest whole number.)

Answer 1

c ≈ 40

Explanation:

Using the sine ratio in the right triangle

sin40° =
`(opposite)/(hypotenuse)` =
`(BC)/(AC)` =
`(26)/(c)` ( multiply both sides by c )

c × sin40° = 26 ( divide both sides by sin40° )

c =
`(26)/(sin40)` ≈ 40 ( to the nearest whole number )
