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
Accepted Solution
A:
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 Answer: A
