Slope = (2+5)/(-3-1) = 7/-4 = -7/4
answer is B -7/4
No, 5/8 is not bigger than 9/10
Answer:
cos P = 53 degrees
cos Q = 37 degrees
Step-by-step explanation:
cos P = 
cos P = 
cos P = 0.60
Cos-1 of 0.60 is 53.13 (round to the nearest whole number)
cos P = 53 degrees
cos Q = 
cos Q = 
cos Q = 0.80
Cos of 0.80 is 36.86 (round to the nearest whole number)
cos Q = 37 degrees
To check anser:
90 + 53 + 37 = 180
180 = 180
Multiply 5x to 3x and -2
multiply 6 to 3x and -2
15x^2-10x+18x-12
15x^2+8x-12
