Answer:
b= 70
Step-by-step explanation:
The sum of the opposite interior angles of a triangle is equal to exterior angle.
a+b = 140
We know that a = b since PQ = RQ The angles opposite the equal sides in an isosceles triangle are equal
b+b = 140
2b =140
Divide by 2
2b/2 =140/2
Non of the above

Answer=B
proving:
503,000 > 10
so we look for a number
less than 10
=5.03 ×10-5
the other three zeros are not
needed.
Thank you
Here are the two pictures.
4x - 3 = 37
+3 +3
4x = 40
Divide by 4 on both sides:
X = 10
