Answer:
<a = 30
<b = 60
<c = 115
Step-by-step explanation:
<a = 30 since they are vertical angles and vertical angles are equal
<a + < b + 90 = 180 since they make a triangle
30 + <b +90 = 180
120 + <b = 180
<b = 180-120
<b = 60
<c + 75 = 180 since they form a straight line
<c = 180-75
<c = 115
Answer:
a=30
b=60
c=105
Step-by-step explanation:
We know a=30 because 30 and a are the same
The middle forms a triangle and triangles are equal to 180
The box indicates that the angle is 90 degrees
180=a+b+90
180=30+90+b
b=60
Angle c is supplementary to 75 so it must equal 180
180=c+75
c=105
