Answer:
m∠EGC=70°
Step-by-step explanation:
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite
so
m∠EGC=(1/2)[arc EC+arc DF]
<u><em>Find the value of x</em></u>
we have
m∠EGC=(7x+7)°
arc EC=50°
arc DF=10x°
substitute and solve for x
(7x+7)°=(1/2)[50°+10x°]
14x+14=50+10x
14x-10x=50-14
4x=36
x=9
<u><em>Find the measure of angle EGC</em></u>
m∠EGC=(7x+7)°
substitute the value of x
m∠EGC=(7(9)+7)°=70°
All of them are statistical

Answer:
4/1
Step-by-step explanation:
i believe thats right since 4/1 is a fraction and it can be simplified to 4
Answer:
40
Step-by-step explanation:
As the total circumference of a circle is 360 degrees, the measure of the unknown arc is 360-150-130=80 degrees.
So, by the inscribed angle theorem, angle 1 measures 40 degrees.
