Solve the right triangle. Round decimals answers to the nearest tenth.
9966 [12]

Answer:

3^2 + x^2 = 9^2

9 + x^2 = 81

x^2 = 72

x = \sqrt{72\\}, which is about 8.5

Cosine X = 3/9

Cosine X = 1/3

angle x= 70.5

If angle x= 70.5, angle z = 19.5 degrees.

Simple geometry please help<br><br> Find KL. Round to the nearest hundredth.
vivado [14]

Answer:

KL ≈ 1.94

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos48° = \frac{adjacent}{hypotenuse} = \frac{JL}{KL} = \frac{1.3}{KL} ( multiply both sides by KL )

KL × cos48° = 1.3 ( divide both sides by cos48° )

KL = \frac{1.3}{cos48} ≈ 1.94 ( to the nearest hundredth )
