USPshnik [31]

Answer:

12\dfrac 12\%

Step by step explanation:

Find the values of a, b and c.
shusha [124]
C= 45
All interior angles of a triangle add to 180. 90+45=135. 180-35=45

a= 45
The top angle of the triangle and a make 90 degrees together. 90-45=45

b= 135
Angle a and b together make 180 (they are supplementary). 180-45=135
