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:
A
Step-by-step explanation:
f(x)=x^2-4x+3
x coordinate: -b/2a
-(-4)/2(1)=4/2=2
and to find the y coordinate just plug in the value of -b/2a for x and solve for y
Center of rhombus bisects 90°.
Sum of angles in triangle = 180°
x + x + 14 + 90 = 180
2x + 104 = 180
2 (x + 52) = 180
x = (180 ÷ 2) - 52
x = 90 - 52
x = 38°
1) 2+12a
2) 8-5x
3)12-3z
i think those are the answers :)
Answer:
$3.45
Step-by-step explanation:
The tip is 15% of his breakfast, that means 15% of 23
That is 15%* 23= 15*23/100= 3.45 $
The tip is $3.45
Have a good day.
