What are the measures of Angles a, b, and c? Show your work and explain your answers. (10 points)

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.

a= 30 degrees (opposite angles are equal)

b= 180-( 90+30) = 60 degrees(angles of a triangle)

c =120 degrees

a = 30

b = 60

c = 105

Step-by-step explanation:

a is vertically opposite to the given angle of 30 degrees.

b is in the lower right corner if the right angle is above angle a.

b + a + 90 = 180 degrees

a + b = 180 -90

a + b = 90

30 - 30 + b = 90 - 30

b = 60

c + 75 = 180

c + 75 - 75 = 180 - 75

c = 105

eve and marks ratios are equivalent
