Answer:
71
Step-by-step explanation:
The square represents 90 degrees.
A triangle’s three angles ALWAYS adds up 180.
To find the missing angle:
180 - 90 = 90
90 - 19 = 71.
Therefore, the answer is 71
Answer:
Option (1)
Step-by-step explanation:
From the picture attached,
Two planes have been given as plane A and plane B.
Two lines 'm' and 'n' are on the plane A.
These lines intersect each other at a point W.
Therefore, point W describes the point of intersection of the lines 'm' and 'n'.
Option (1) will be the correct option.
Answer:
angle b is 30 degrees
Step-by-step explanation:
a right angle is 90 degrees so you can do 90 -60 witch gets you 30 degrees
