Answer:
D 73º
Step-by-step explanation:
Total angles
a = (sides - 2) * 180
a = (5 - 2) * 180
a = 540
-------------------
Missing angle
x = 540 - (104 + 118 + 96 + 115)
x = 107
a is supplementary to x
m∠A = 180 - 107
m∠A = 73º
<h3>x intercept is -3 and y intercept is 9</h3>
<em><u>Solution:</u></em>
<em><u>Given equation of line is:</u></em>
y = 3x + 9
<u>Find the x intercept:</u>
Substitute y = 0 in given
0 = 3x + 9
3x = -9
Divide both sides by 3
x = -3
Thus x intercept is -3
<u>Find the y intercept:</u>
Substitute x = 0 in given
y = 3(0) + 9
y = 0 + 9
y = 9
Thus the y intercept is 9
They are not
It goes from
0/0 1/3 2/5 3/6(or 1/2) which are not the same. This makes them not proportional to one another. (I think)
Tbh ion even know ................
Ok so you would start by getting rid of the fraction. You should know the steps for that by now but here this is what it would look like
3y/4+10=2y/4 Simplify
3y/4+10=1y/210=-1y I really simplified the last part but this is what it looks like:
-
= -1y
10=-1yy=-10
