Simplify 5x-3-7 to -2x-3
-2x-3=15-x
Add 2x on both sides
−3=15−x+2x
Simplify 15-x+2x to 15+x
−3=15+x
Subtract 15 on both sides
-3-15=x
Simplify -3-15 to -18
-18=x
X=-18

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°
