All of the angles add up to 360 degrees.
180(4-2) = 360
9x+1+5x-12+8x+61
Add up all the like terms
22x+50= 360
x=14.1
We are going to add up all of the angles together and subtract them by 360 in order to find the measurement of the missing angle.
Angle C: 9(14.1) + 1 = 127.9
Angle D: 5(14.1) - 12 = 58.5
Angle A: 8(14.1) + 61 = 173.8
All of these angles add up to 360
This means that angle D is 0 degrees since all of the other angles already add up to 360.
<u>Answer</u>
0 degrees

Hello:<span>
the equation is : y = ax+b
the slope is a : a×(-3/2) = -1......(
perpendicular to a line with a slope of -3/2)
a = 2/3 y=(2/3)x+b
the line that passes through (-2, -2) :- 2 =
(2/3)(-2)+b
b = -2/3
<span> the equation is : y = (2/3)x-2/3</span></span>
<span><span>y =(2/3)(x-1)</span></span>
Answer:

Step-by-step explanation:




Basically, you need to add a number to both sides so that you can reduce the left side to a square. In this case, you add 4.
