Answer:
40°, 60°, and 80°
Step-by-step explanation:
We know that the sum of the angles of a triangle is equal to 180°.
We can use this equation to solve for these angles:
180 = 2x + 3x + 4x
180 = 9x
20 = x
Then substitute the solution in for x to solve for the angles:
2(20) = 40°
3(20) = 60°
4(20) = 80°
Therefore, the angles are 40°, 60°, and 80°.
Answer:
m = 
Step-by-step explanation:
Given
= 
( cross- multiply )
6m = 21 ( divide both sides by 6 )
m = 
= ( = 3.5 in decimal form )
The answer is going 5 - 2x = 3
