Answer:

m∠K = 36°

m∠L = 54°

m∠M = 90°

Step-by-step explanation:

         A triangle's angles add up to 180 degrees. We will add together all the angles and set them equal to 180. Then, we will solve for x. Lastly, we will solve for the angle measurements.

-> The little "box" in angle M means that it is equal to 90°

90° + (2x + 42)° + (4x + 12)° = 180°

90° + 42° + 12° + 2x° + 4x°= 180°

144° + 6x°= 180°

6x° = 36°

x = 6°

[m∠K]

4x + 12

4(6) + 12

36°

[m∠L]

2x + 42

2(6) + 42

54°

What is the solution to the system of equations?
Sergio039 [100]
The value for x is already given; x = -2

Substitute -2 in for x in the second equation.

y = 2/3(-2) + 3
y = -4/3 + 3
y = 5/3 

The final answer is (-2, 5/3).

How would i get the area and perimeter of this?
Dmitry [639]

Answer:

Perimeter: 10.1 m

Area: 6.16 m^2

Step-by-step explanation:

For perimeter just add up all the sides except for 2.8 m since that is set aside for area.

For area multiply the length 2.2 by the height 2.8 m. The reason behind this is that using a slanted height makes know sense sine when you measure things they should be perfectly as possible vertical
