Answer:
170°
Step-by-step explanation:
To convert from radians to degrees
degree measure = radian measure × , thus
degree = ×
Cancel π on numerator/denominator and 18/ 180 by 18
degree measure = = 17 × 10 = 170°
Answer:
It is 23
Step-by-step explanation:
BC= FE
(x-4)=19
Therefore x= 23
Answer:
20
Step-by-step explanation:
simple 20(4)-15(4)=80-60=20
Perform the operation in the choices to determine the coefficients of the terms.
(Addition) -4x - 1 + 2x + 4 = -2x + 3
(Subtraction) -4x - 1 - (2x + 4) = -6x - 5
(Multiplication) (-4x - 1)(2x + 4) = -8x² -18x -4
Thus, the answer is multiplication as it gives a numerical coefficient equal to -18.
