Answer:
Step-by-step explanation:
4b - 16b + 12 = 48
-12b + 12 = 48
-12b = 36
b = -3
The area formula of a triangle is 1/2 ×base ×height
so 1/2×3 in ×8 in ---> 1/2×24 in = 12 in
Rule: with any inscribed quadrilateral, the opposite angles are supplementary (they add to 180 degrees)
Based on that rule, we can say
d+100 = 180
d+100-100 = 180-100
d = 80
Answer: 80
If you look at the model RM is the same length as PM. PM=10 so RM=10.
