Step-by-step explanation:
a)<PTR=90°(angles in a semicircle)
<RPT=50°
<PRT + <PTR + <RPT=180°(angles in a triangle)
<PRT=180-(90+50)
<PRT=40°
b)From ∆QTS
<TQS = <RTP =50°
<QTS=180-(50+28)
<QTS=102°
c)<QTR=180-(90+50)
<QTR=40°
Coefficients: 18
Constants: 7
Variable (if u need help on this): X
A, or 122. When you know those two lines are parallel with that one line intersecting them both, their larger angles will be equal and their smaller angles will also be equal to each other.
X equal to X= -5/2 (The denominator is 2)

Answer:
5/36
Step-by-step explanation:
Colin's fraction of the prize is ...
5/(3+4+5) = 5/12
1/3 of that is ...
(1/3)(5/12) = 5/36
Colin gave 5/36 of the prize to charity.
