BC= 39
Explanation:
4z+4z+3z+3+3z+3=174
8z+6z+6=174
14z+6=174
Subtract 6 from both sides
14z=168
Z=12
So then 3*12+3=39
And you can check by doing 39+39+48+48
And it equals 174
Slope is 5
Y intersect is 0
Y= 5x
Supplementary means they equal 180 when added. Therefore:
X+56+3x=180
Combine common units
4x+56=180
Subtract 56 from both sides
4x=124
Divide by 4
X=31
Now we know the smaller angle is 31 degrees. Now we plug that into the larger angle:
3(31)+56
93+56
149
The larger angle is 149 degrees.
I hope this Helps!
16 units. Start from -2 and count up to 14. Basically -2+2+2+2+2+2+2+2+2+2 since the scale is by 2
