There is 180degree in a triangle
Answer:
102 and 109
Step-by-step explanation:
create an equation to solve:
(x-7) + x = 225
2x -7 = 225
<u> +7 +7</u><u> </u><u> </u> add 7 to both sides
<u>2x</u> = <u>218</u>
2 2 divide both sides by 2
x = 109
<u>109 is the first number</u>
then you solve for the other number
x-7= ?
109 - 7 = 102
<u>102 is the 2nd number</u>
We know at centroid medians bisect each other in the ratio 2:1.
