Answer: angle y is 50°
Step-by-step explanation:
t + 2t - 30 = 90
3t -30 = 90
3t = 90+30
t = 120/3 = 40 = angle X
Angle y = 2t-30
y = 2*40-30
=80-30 = 50
Answer: 0.8 radians
Step-by-step explanation:
To solve this exercise you must apply the formula shown below:

Where S is the arc lenght, r is the radius of the circle and
is the central angle in radians.
Solve for the central angle:

Now, when you susbtitute the value of the arc length and the radius, you obtain that the central angle is:
