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°
Answer:
2 13/48 or 109/48
Step-by-step explanation:
Find the least common denominator
16 * 3 = 48
12 * 4 = 48
8 * 6 = 48
Convert all fractions into the common denominator of 48
33/48 + 40/48 + 36/48
Add
109/48
Simplify
2 13/48

Answer:
the answer is 124.52
Cut it into 3 shapes, the bottom half circle, the top rectangle, and the middle rectangle
top rectangle:
A= bh
A= 4x10
A=40
middle rectangle:
A=bh
A=4x7
A= 28
Half circle:
A= πxr^2
A=πx6x6
A=πx36
A=56.52
Add it all up and you get the answer above
Plz review and thank :)
