Question

Refer to the figure below to answer the following questions: (a) What is the value of "x"? (b) Angle 4 Given ml 72 1\6x + 23 is equal to how many degrees? _ 4x - 34 5. 6

Answer 1

we get that

$\begin{gathered} 4x-3+6x+23=90\rightarrow \\ 10x+20=90 \\ 10x=70 \\ x=\frac{70}{10}=7 \end{gathered}$

so we have x=7

the angle 4 is equal to

$m\angle4=90-(4\cdot7-3)=90-25=65^{\circ}$
