Answer:

26

Step-by-step explanation:

cosθ = adjacent / hypotenuse

cos(26) = 18 / x

x= 18 / cos(26)

x= 27.82418 ≈ 20 (to nearest tenth)

Answer:

x ≈ 20

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos26° = \frac{adjacent}{hypotenuse} = \frac{18}{x} ( multiply both sides by x )

x × cos26° = 18 ( divide both sides by cos26° )

x = \frac{18}{cos26} ≈ 20.0 ( to the nearest tenth )

Use angle relationships to find the value of x.
Juli2301 [7.4K]

Answer:

x=12.

Step-by-step explanation:

Let's get this straight out of the way, the 3 angles of a triangle ALWAYS add up to 180. Now that that's said, lets begin. Since the opposing side of an angle is the same as the regular side, we simplify to get: 5x+120=180. 180-120=60. so 5x=60. 60/5=12. so x=12.

If <a is 89.5, what is the measure of its complementary angle?​
Pachacha [2.7K]

Answer:

The complement of an angle is what, when added to it, equals 90 degrees (90°). For example, in your problem, 90°-85°=5°. This means that the complement of 85° is 5°, since they add up to equal 90 degrees a right angle.

The supplement of an angle is what, when added to it, equals 180 degrees.

For example, in your problem, 180°-85°=95°. This means that the supplement of 85° is 95°, since they add up to equal 180 degrees a straight angle.
