Answer:
C
Step-by-step explanation:
Since the 7 swim teachers had about the same amount of students, you can divide 137 by 7, which comes out to about 20.
Answer:
D
Step-by-step explanation:
Using sine rule
a/sin A ＝b/sin B
8/sin90° ＝ x/sin60°
8 * sin60° ＝ x
x ＝
To find the median cancel out numbers on both sides, until one is left in the middle and if there are two in the middle add them up and divide by two.
So in this case the median is
53+78
131 / 2
65.5
Answer:
62°
Step-by-step explanation:
Complementary angles by definition are two or more angles that add up to 90°. So we must do 90°-62° to get the missing angle which is 62°.
Hope that helped.
The answer is -7
The arrows both point toward the left side, and sine there are seven spaces the arrows are going through, you subtract 7 spaces and get -7
Hope that helps.
