-73.35. You have to use the distributive property and multiply -9 x 8.15
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: -20</h3>
==========================================================
Work Shown:
Let x be the location of E on the number line.
Since C is the midpoint of E and F, this means we can find C's location by adding E and F together and dividing that sum by 2
midpoint = (endpoint1 + endpoint2)/2
C = (E+F)/2
Plug in E = x, C = -8 and F = 4. Then solve for x
C = (E+F)/2
-8 = (x+4)/2
(x+4)/2 = -8
x+4 = 2(-8) .... multiplying both sides by 2
x+4 = -16
x = -16-4 .... subtract 4 from both sides
x = -20
The location of point E on the number line is -20
-------------
As a check, lets add E and F to get E+F = -20+4 = -16
Then cut this in half to get -16/2 = -8, which is the proper location of point C
This confirms our answer.
The answer is 15.9 because 3.9+111=15.9
