Answer:
2) 11
3) 21
4) 7
Step-by-step explanation:
2) (-6) -(-17) = 17 - 6 = 11
3) 19 - (-2) = 19 + 2 = 21
4) (-13) + 20 = 20 - 13 = 7
Step-by-step explanation:
So, you have to get angle under 130° angle:
180°-130°= 50°
And you get X
x=180°-(113°+50°)
x=180°- 163°
x=17°
Answer:
4/5
Step-by-step explanation:
Sin is opposite / hypotenuse
Sin x= 16/20
16/20= 4/5
Answer: -16
Step-by-step explanation:
49 would be the result of -7 squared. Due to the fact it is negative, it would cancel out to be positive.
For the numerator, 49-1 is equivalent to 48.
48/x+4
-7+4 = -3
48/-3
= -16
