Let ∠RTS=∠RST = a (say)
∠QUA=∠QSU= b(say)
then we know , at point S, a+40+b=180. so, a+b=140 we'll use this later.
consider trianglePQR, ∠P+∠Q+∠R=180
i.e.P+(180-2b)+(180-2a)=180
P+180+180-2(a+b)=180 ⇒P+180-2(a+b)=0 ⇒P=2(140)- 180=280-180=100
hence,answer is E
Answer:
Olga's mistake was in Step 3 because she divided the entire equation by 3 instead of dividing it by 1/3.
Step-by-step explanation:
Hello there!
Just double the given sides!
(18*2)+(12*2)=60 cm.
There you are!

637 is the answer because our value is 980 we all know the unknown value with x for the step above 980 and 100% and 65% is the result in a pair of a simple equations
Answer:
x= 24
/7
Step-by-step explanation:
2
/3x−2= 2/7
add 2 both sides
multiply by both sides by 3/2.
