1.
a)
S=W
2x+5 = x+15
2x-x = 15-5
x= 10
W= x+15
W= 10+15
m∠W= 25
b)
WI=HS
3y+3 = y+13
3y-y = 13-3
2y = 10
y = 5
HS= y+13
= 5+13
HS= 18
c)
d)
2.
14= 2x+10 + 3x-2 / 2
14= 5x+8 / 2
(2) 14= 5x+8 (2)
28= 5x+8
-5x=-28+8
x= 4
OS= 3x- 2
OS= 3(4)-2
OS= 12-2
OS= 10
PT= 2x+10
PT= 2(4) +10
PT= 8+10
PT= 18
∠P+∠O =180°
2x+5 + 3x-10= 180
5x-5 =180
5x= 180+5
5x= 185
X= 37
P= 2x+5
P=2(37)+5
P= 74+5
P= 79°
∠P = ∠T
∠T= 79°
