Answer:
Step-by-step explanation:
If the ratio of triangle = 3:4:2
Total ratio = 3+4+2 = 9
The sum of angle in a triangle is 180°
1st angle= 3/9 × 180 = 2 × 20 = 60°
2nd angle= 4/9 × 180 = 4 × 20 = 80°
3rd angle= 2/9 × 180 = 2 × 20 = 40°

Answer:
x = 5/13
Step-by-step explanation:
Answer:
x=10
y=2
Step-by-step explanation:
1)add the equations and find what x is.
x-y=8
+x+y=12
—————
2x=20
— —
2 2
x=10
3)fill in x for the second equation.
x+y=12
since x=10,replace x with 10.
10+y=12.
subtract 19 from both sides.
10+y=12
-10 -10
—————-
y=2
