Answer:
Step-by-step explanation:
If the ratio of triangle = 6:3:7
Total ratio = 6+3+7 = 16
The sum of angle in a triangle is 180°
1st angle= 6/16 × 180 = 6 × 11.25
= 67.5°
2nd angle= 3/16 × 180 = 3 × 11.25
= 33.75°
3rd angle= 7/16 × 180 = 7 × 11.25
= 78.75°
Largest is 78.75° and smallest is 33.75°
Answer:
8
Step-by-step explanation:

Been a bit since i’ve done this kind of problem.
X+4=20
X is the number of hours needed to work, while 4 is the hours already there.
Answer:
C) 
Step-by-step explanation:
0.51 repeating decimal
x= 0.51515151
multiply by 100 on both sides
100x = 51.515151.........
x= 0.515151...............
--------------------------------------------(subtract)
99x = 51
divide by 99 on both sides

divide both sides by 3

You have to get Y on a side by itsself than divide by 3 and you end up with y=-4+9x
