use a trigonometric ratio to find the value of x. round your answer to nearest tentha. 6.2 cm b. 12.7 cmc. 15.5 cmd. 10.9 cm

The trigonometry ratio that we shall use to solve the question will be:
tan θ=opposite/adjacent
where:
opposite=8.9 cm
adjacent =x cm
θ=55°
plugging the values and simplifying we obtain:
tan 55=8.9/x
thus
x=8.9/tan55
x=6.23 cm~6.2 cm
