Question

M angle 3= 31°. Find m angle 4 (complementary angle)

Answer 1

Hi, there.

  ________

$\boxed{\begin{minipage}{8cm} Complementary angles \\ Complementary angles are angles whose sum \\ is 90^\circ. \text{Using this info, let's consider this:} \\ \text{If an angle's measure is 31 degrees, what's} \\ \text{its \ complement?}\end{minipage}}$

$\text{Set up an equation, letting a be the unknown angle}$

$\bold{a+31=90}\\\text{Subtract 31 from both sides}\\\bold{a=59}$

Hope the answer - and explanation - made sense,

happy studying!!
