Answer:
100
Step-by-step explanation:
The measure of an arc is twice the measure of the inscribed angle that intercepts it. The arc y° is intercepted by an inscribed angle marked 50°, so ...
y = 100
Answer:
-1.25
-1.30
-1.50
-1.75
Step-by-step explanation:
There's more than 4 correct answers but...
Answer:
m∠2=31
m∠3=65
m∠1=?
Notice that measure of angle 2,3 and the angle that's next to angle 1 will form a triangle. Let's name the angle next to 1 to be x.
31+65+x = 180
96+x = 180
x = 180-96
x = 84
Now, you can easily find the m∠1.
84+m∠1 = 180 (REASON: Linear pair)
m∠1 = 180-84
m∠1 = 96
