Answer:
∠RPQ = 53°
Step-by-step explanation:
∠SPR and ∠RPQ are complementary, meaning that they add up to 90°. So,
∠SPR + ∠RPQ = 90°
We know that ∠SPR = 37°, so
37° + ∠RPQ = 90°
∠RPQ = 90° - 37°
∠RPQ = 53°
Here are all the possible statements we can gather:
B. 50% of the students earned a score of 80 or higher.
E. The highest score was 38 points greater than the lower score. (Since range is defined as the difference between the highest number and the lowest number)
Hope my answer has helped.
Answer:
a. 8
b. 61, 23, 84
Step-by-step explanation:
As we can see, point S is between points R and T, therefore:
- RS + ST = RT
- 7y + 5 + 2y + 7 = 14y - 28
- 9y + 12 = 14y - 28
- 14y - 9y = 12 + 28
- 5y = 40
- y = 40/5
- y = 8
------------
- RS = 7y+5 = 61
- ST = 2y + 7= 23
- RT = 14y - 28 = 84
