Question

help please I don't understand
What are the measures of Angles a, b, and c? Show your work and explain your answers.

Two straight lines intersect at a point to form angle a. The measure of the angle opposite to angle a is 30 degrees. Angle a is the angle of a right triangle having another angle equal to b. A triangle with one angle labeled c is on the left of the figure. The angle adjacent to c is labeled 75 degrees.

Answer 1

angle a is equal to the angle 30,

the angle (75 + c) = 180 as it's a straight line
so c = 105
in the right triangle the sum of all the angles = 180
so 30 + b + 90 = 180
b = 60
