1) Δ ABC
m∠B + m∠C + m∠BAC = 180⁰
2) m∠DAB + m∠BAC = 180⁰ because m∠DAB and m∠BAC are supplementary angles.
3) m∠B + m∠C + m∠BAC = m∠DAB + m∠BAC
m∠B + m∠C = m∠DAB
32⁰ + x = 98⁰
x=98 - 32 = 66 ⁰
Answer: A. 66⁰.
Basically you explain what your answer is and how you got it then you should be good!
Answer:
Final price: $14.99
Step-by-step explanation:
Discount= original price x discount % / 100
Discount= 19.99 x 25/ 100
Discount= 499.75/100
You save= $4.9975
Final Price= original price - discount
Final price= 19.99 - 4.9975
Final Price= $14.9925
Final Price= $14.99
Average rate of change is slope. The equation for slope is m=(y2-y1)/(x2-x1). (x2, y2) will be (5, 1) and (x1, y1) will be (-1, 7). Plug in and solve:
(7-1)/(5--1)
6/6
1
Hope this helps!!
