Answer: No
Step-by-step explanation: if you mean the measure of a is 3, the measure of b is 9 and the measure of c is 5, c being the hypotenuse then the answer is no because the the sides of a and b must be less than the measure of c. If 5 wasn’t the hypotenuse then the answer would be different.
(KEEP IN MIND THAT IF 9 IS THE HYPOTENUSE THEN THE ANSWER IS YES)
Hope this helps! :)
Answer:
89
Step-by-step explanation:
Given that the class has 28 students has 7 juniors and 21 seniors
mean score of the juniors = 73
Therefore, total score of junior = 73 × 7
= 511
mean score of seniors = y
Total score of seniors = 21y
Total score of the class = 511 + 21y
Mean score of the class = 85
Total score of the class = 85 × 28
= 2380
therefore,
511 + 21y = 2380
21y = 2380 -511
21y = 1869
y = 1869/21
y = 89
You need to use the "mean". -4 + -3 + -5= -12 ÷ by 3 = -4°. the answer is -4
