Use the cosine ratio or the inverse cosine to solve forx. Round your answer to the nearest tenth.

Answer:
The value of x = 175.4 mm
Step-by-step explanation:
The given triangle is a right-angled triangle.
Given
Ф = 70
To determine
hypotenuse = x
We know that the trigonometric cosine ratio can be represented as
cos Ф = adjacent / hypotenuse
here
substituting the values
cos Ф = adjacent / hypotenuse
cos 70 = 60 / x
x = 60 / cos 70
x = 175.4 mm
Therefore, the value of x = 175.4 mm
