The value of y is 50
The angle measurement of angle AOB is 100°
<h3>Circle Geometry </h3>
From the question, we are to determine the value of y and the measure of angle AOB
From one the circle theorems, we have that
Angles in the <u>same segment</u> are equal
In the given diagram, x° and y° are angles in the same segment
∴ x° = y°
From the given information,
x = 50
∴ y = 50
Hence, the value of y is 50
Also, from another circle theorem,
Angle at the <u>center</u> is twice the angle at the <u>circumference</u>
∴ ∠AOB = 2x° = 2y°
Then,
∠AOB = 2×50°
∠AOB = 100°
Hence, the angle measurement of angle AOB is 100°

Answer:
20
Step-by-step explanation:
4x + 10 = 90° cause it's hypotenuse
4x = 90-10
x = 80÷4
= 20

Answer:
2 is your answer
Step-by-step explanation:
If h(x)= 5 then 5= 2x +1
so 5 = 2x + 1
-1 -1 on both sides
then 2x = 4
2 2 divide by 2
which x = 2
