Answer:
x=17°
Step-by-step explanation:
163+x=180 (L.P)
x=180-163
x=17°
Consetive integers are 1 apart
they are
x,x+1,x+2
3 times the first added to the last is 22
3x+x+2=22
combine like terms
4x+2=22
minus 2 both sides
4x=20
divide both sides by 4
x=5
x+1=6
x+2=7
the numbers are 5,6,7
P = 2l + 2w
Subtract both sides by 2w
P - 2w = 2l
Divide both sides by 2
(P - 2w) / 2 = l
In our problem,
w = 7 in
P = 42 in
Let's plug our values into the formula above.
(42 in - 2(7 in) / 2 = l
(42 in - 14 in) / 2 = l
28 / 2 = l
14 in = length
