Question
x and y are complementary angles and y and z are
supplementary angles. Find the value of z if m∠x = 43° .
Hint:
Use the property of complementary angles and supplementary angles.
The correct answer is: Hence the value of ∠z=133°.
Complete step by step solution:
When the sum of two angles is equal to 90° , then they are called complementary
angles.
When the sum of two angles is equal to 180° , then they are called supplimentary
angles.
