Can someone tell me if this is right for the arc

BC is a minor arc

Step-by-step explanation:

Just as an extra piece of information that can help us:

Knowing that the diameter splits a circle into halfs, it's degree measure is half of the degree measure of the whole circle: 360/2 = 180 degrees.

This means that diameter AC consists of a 180 degree measure, helping us in the sense that:

mBC + mBA = mAC

mBC + 70 = 180

mBC = 180 - 70

mBC = 110 degrees

Now the mBC to the mBEC is 110: 250 such that we know arc BC is smaller in size as degree measure is proportional to circumference length. Knowing it is smaller in length, BC is thus a minor arc.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
