Solve the proportional equation
5/12 = x/15

6.25.

Step-by-step explanation:

Let's put your question into a proper proportional form, because it is a ratio that is equal.

To solve proportions, you have to cross-multiply in the direction that has numbers, which is 5 and 15, then divide to 12.

The answer you should get by doing this is 6.25.

x=6.25

Step-by-step explanation:

Cross multiply

5/12=x/15

12*x=15*5

12x=75

Divide both sides by 12 to isolate the variable x

x=6.25

Or, multiply both sides by 15 to "reverse" the division being done to x

5/12=x/15

15*5/12=x/15*15

6.25=x

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
