Question

ZA and ZB are supplementary angles. If mZA= (3x + 9)° and m ZB = (6x + 27)°, then find the measure of ZA. =

Answer 1

Given

ZA and ZB are supplementary angles. If mZA= (3x + 9)° and m ZB = (6x + 27)°,

Solution

Two angles are called supplementary when their measures add up to 180 degrees

Now,

`\begin{gathered} m\measuredangle A=(3x+9)^0 \\ \\ m\measuredangle A=(3*16)+9)^0 \\ \\ m\measuredangle A=(48+9)^0 \\ m\measuredangle A=57^0 \end{gathered}`
