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
b= 70
Answer:
Three 60 degree angles would equal 180 degrees
Step-by-step explanation:
Answer:Thus, a product that normally costs $20 with a 40 percent discount will cost you $12.00, and you saved $8.00. You can also calculate how much you save by simply moving the period in 40.00 percent two spaces to the left, and then multiply the result by $20 as follows: $20 x . 40 = $8.00 savings.
