Use trigonometric ratios to solve for X to the nearest tenth
Elan Coil [88]

Answer: x = 106.5

<u>Step-by-step explanation:</u>

You can use either sin or cos.  I will use cos.

cos\ \theta=\dfrac{adjacent}{hypotenuse}\\\\\\cos\ 62^o=\dfrac{50}{x}\\\\\\x\ cos\ 62^o=50\\\\\\x=\dfrac{50}{cos\ 62^o}\\\\\\.\quad=\dfrac{50}{0.469}\\\\\\.\quad=106.5

Find the value of x. Show all work.
Mashutka [201]

Answer:

x = -8°

Step-by-step explanation:

Angle 2

Since the triangle is isosceles, Angle 2 is the same as the missing angle

So angle 2 would be:

180 - 34 = 2(angle 2)

So 146 = 2(x + 81)

146 = 2x + 162

146 - 2x = 162

-2x = 16

x = -8

Check

146 = 2(-8+81)

146 = 2(73)

146 = 146

Correct!

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!
