Hi there!
The answer to this question is: A. 55 degrees
Step-by-step explanation:
Using a the triangle angle sum theorem, you know all angles of triangle add up to 180.
In picture you are given two angles, 90 and 35
all you do is add them to get 125
then you subtract 125 from 180 to get 55
so in other words your final answer should be 55
Y varies inversely with x.
⇒ y = k/x
When y = 5, x = 50
5 = k/50
k = 50 x 5 = 250
Equation: y = 250/x
When x = 10
y = 250/10 = 25
Answer: k = 250, y = 25 when x = 10
