to find the slope of P, use the formula (y2-y1)/(x2-x1)
(8-13)/(9-2) gives you -5/7
a perpendicular line has the opposite reciprocal slope so it is positive 7/5 or 1 2/5
The answer is B. 80.8
Step-by-step explanation:
To do this, divide the numerator by the denominator. The result is the decimal form of the ratio. For example, convert 7:2 to a decimal value.
Answer:
125 degree
As m // n, so angle 2 and angle 6 is the same so angle 2 = 55 degree, then angle 1 + angle 2 = 180 degree, so angle 1 = 180 - 55 = 125 degree.
