Question

A and B are supplementary angles. If m A = (x + 15)° and m

Answer 1

Answer:

76 degrees

Step-by-step explanation:

We know that supplementary angles equal 180 degrees. So, set up the equations:

$180=(x+15)+(x-13)$

$180=(2x+2)$

$178=2x$

$x=89$

Then, you just plug 89 back into ZB, and simplify:

$(89-13)$

$=76$

So, the measurement of angle ZB is 76 degrees.
