D-(-17)=-14
d+17=-14
d=-14-17
d=-31
answer is A
89+91=180
137+X/2=91 EG= 45
EG= 45 />DE= 360-137-61-45=117
Answer:
x = 12, so PTQ = 40 deg
Step-by-step explanation:
first, because the two are vertically opposite, they are equal, write a formula for this:
x + 28 = 2x + 16 (minus 2x from both sides)
-1x + 28 = 16 (minus 28 from both sides)
-1x = -12 (divide both sides by -1)
x = 12
sub into formula:
12 + 28 = 40
