Answer:
x=-19/2
Step-by-step explanation:
3(x+6)+6x+9=7x+8
3x+18+6x+9=7x+8
9x+27=7x+8
9x+27-7x=8
2x+27=8
2x=8-27
2x=-19
x=-19/2
The denominator is the bottom number in a fraction or the total number of parts so 2, 8, 8, 8, and 8

Answer:
12°, 78°, 90°
Step-by-step explanation:
let the third angle be x then the second angle is 7x - 6
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
x + 7x - 6 + 90 = 180, that is
8x + 84 = 180 ( subtract 84 from both sides )
8x = 96 ( divide both sides by 8 )
x = 12
Thus second angle = 12° and third = 7(12) - 6 = 84 - 6 = 78°
The 3 angles are 12°, 78° and 90°
