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:
B. 30 ft
Step-by-step explanation:
The ladder is 32 ft long
The angle of elevation of the ladder is 70°
The height (h) of the top of the ladder to the ground is what we are to find.
= sin 70°
h = 32 × sin 70° = 30.07016387 or 30 ft (rounded off to nearest feet)
Answer:
Step-by-step explanation:
your not giving any percentages for us to use
The odds against picking an i are 5:3, since there are 5 letters that are not i and 3 letters that are.
Answer:
n=13
Step-by-step explanation:
n-29-33=-49
Always work left to write in these types of equation, so subtract -29-33 to get -62:
n-29-33=-49
n-62=-49
Add 62 to both sides:
n-62=-49
+62 <u>+62</u>
n = 13
