Question

A home has a triangular backyard. The second angle of the triangle is 7 degrees more than the first angle. The third angle is 8 degrees more than three times the first angle. Find the angles of the triangular backyard

Answer 1

got pic?

Answer 2

what?

Answer 3

hmmm I see

Answer 4

alrite
so.. the backyard is triangular
let's say angles
a,b and c
so angle "a" is the first one

"second angle of the triangle is 7 degrees more than the first angle"
meaning, b is 7 more than "a", or \(\bf b = a+7\)

" third angle is 8 degrees more than three times the first angle"
meaning, "c" is 8 more than "a", or a + 8, BUT is really 8 more than 3 times "a"
so \(\bf c = 3a+8\)

Answer 5

recall, that the sum of all internal angles in a triangle, are \(\bf 180^o\)
