⇒ tan x° = 3/5

⇒ x = tan⁻¹ (0.6)

⇒ x = <u>31°</u>

1 16) Line x is parallel to line y. What is the measure of angle 6? HELP PLEEEEEASE
Setler [38]

Answer:

\angle 6 = 93

Step-by-step explanation:

\angle 5 = 87 by properties of parallel lines

\angle 5 + \angle 6 = 180 because they form a straight angle

87 + \angle 6 = 180\\\\\angle 6 = 180-87\\\\\angle 6 = 180 - 80 - 7\\\\\angle 6 = 100 - 7\\\\\angle 6 = 93 \longleftarrow
