The measures of one of the angles of a triangle is 35.the sum of the measures of the other two angles is 145 and the difference between their measures is 15. what are the measures of the unknown angles

x=80 and y=65

Step-by-step explanation:

Let one angle be x and the other be y

x+y=145     (1)

x-y=15       (2)

Adding both eqs

x+y+x-y=145+15

2x=160

x=160/2

x=80

Putting value of x in 1

80+y=145

y=145-80

y=65

Now

x+y+z=180 where z=35

80+65+35=180

180=180

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
