Answer:
180- 148 = 32 (the measure of the angle thats supplementary to the exterior
180 - 56 -32 =92 (180 is the interior triangle angle sum, subtract the known angles to discover the unknown angle.
angle h = 92 degrees

Answer:
x = -12
Step-by-step explanation:
The particular identity you want to use is

Then

Expand the binomial to get

Use the identity again to write

and so


Answer:
y=2x-3
Step-by-step explanation:
y-y1=m(x-x1)
y-(-9)=2(x-(-3))
y+9=2(x+3)
y=2x+6-9
y=2x-3
P/L=4/7 and P=L-12 so
(L-12)/L=4/7 multiply both sides by 7
(7L-84)/L=4 multiply both sides by L
7L-84=4L subtract 4L from both sides
3L-84=0 add 84 to both sides
3L=84 divide both sides by 3
L=28, and since P=L-12
P=16
So they had 28+16 = £44 in total.
