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°.
If the angles are below 90 degrees this would make this triangle an acute triangle
Answer:
This is the observed variable in an experiment or study whose changes are determined by the presence or degree of one or more independent variables. When graphed, this variable is usually on the vertical axis.
Step-by-step explanation:
This is a vertical line an all vertical lines have an undefined slope.
