Question

Find the value of x if ∡A and ∡B are supplementary angles.

Answer 1

Answer:

$x = 30.5$

Step-by-step explanation:

Two angles are supplementary when they add up to 180°.

So we know that:

$C + D = 180$

Supplanting we get:

$(3x-44) + (5x-20) = 180$

We add up the X's.

$8x-44-20 = 180$

$8x-64 = 180$

Then we send 64 to the other side adding:

$8x = 180+64$

$8x = 180+64$

$8x = 244$

And then the 8 goes dividing:

$x = 244 : 8$

$x = 30.5$
