X = 38°
Step-by-step explanation:
The sum of the inner angles of a triangle is 180 degrees
Then.. :
136+ x= 180
180- 136= x
X= 44
88 + 44 + x = 180
142+ x = 180
X= 180-142
X = 38°

ANSWER

EXPLANATION
The given angle is 870°.
870°-360°-360°=150°
This means that:
870° is coterminal with 150°, hence its terminal side is in the second quadrant.
It makes an acute angle of 30° with the x-axis.
Note that cotangent is negative in the second quadrant,
Hence,

The first option is correct.
Answer:
0.002%
Step-by-step explanation:
10/5,000 = 0.002
Hope this helps!
Add 13 to both sides, which leaves you with k=42.
Answer: $42.60
Step-by-step explanation:The 20% of $35.50 is $7.10. Then, you add $7.10 to $35.50, that will be $42.60.
