The difference between two numbers is 10 and their sum is four times the smaller number find the two numbers.

A = larger number

B = smaller number

A -B = 10

A + B = 4B

A=10+B

10+B+B = 4B

10 +2B = 4B

10=2B

B = 10/2 = 5

A = 10+5 =15

15-5 =10

15+5 = 20, 4*5 = 20

 the numbers are 5 & 15

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
