What is the area of an acute angle
2 answers:
The acute angle inside the triangle is 57 degrees. The one labeled “1” is 123 degrees.
Answer:
123
Step-by-step explanation:
The interior angles of a triangle add up to 180.
So...
60 + 63 = 123
180 - 123 = 57
Then, since angle 1 is complementary to the angle that measures 57, we subtract it from 180.
180 - 57 = 123.
Angle 1 is 123.
