(-9-(-29))/(7-15)
20/-8
-2 1/2
The slope is -2 1/2
Sine 35 degrees = x / 20
x = sine 35 degrees * 20
x = .57358 * 20
x = 11.4716
First, change the mixed fraction into improper fraction. Change the whole number into a fraction, and add.
1 8/11 = 11/11 + 8/11 = 19/11
To find the reciprocal, flip the fraction.
The reciprocal of 19/11 is 11/19
