Math help will give brainliest<br>X is 7 but I got m angle D wrong
STatiana [176]
Answers: 
x = 7
The measure of angle D is 14 degrees

-----------------------------------------------
-----------------------------------------------

Angle C and angle D are complementary, which means they add to 90 degrees. 

(angle C) + (angle D) = 90
(12x-8) + (3x-7) = 90
12x-8 + 3x-7 = 90
(12x+3x) + (-8-7) = 90
15x-15 = 90
15x-15+15 = 90+15
15x = 105
15x/15 = 105/15
x = 7

So you have the correct x value. Nice work.

Now use this x value to find the measure of angle D

angle D = 3*x - 7
angle D = 3*7 - 7
angle D = 21 - 7
angle D = 14 degrees
