Find the two angles and show work!!!
USPshnik [31]

Answer:

x=23.5

Step-by-step explanation:

90=25-x/2+18

combine like terms

90=43-x/2

subtract 43 from both sides

47= -×/2

47/2= 23.5

x=23.5

or

90-25= 65

65-18=47

47/2=23.5

A line passes through the point (-7,8) and has a slope of 1
Mila [183]

Answer:

y - 8 = x + 7

Step-by-step explanation:

To write the equation of a line use the point slope form. Substitute m = 1 and (-7,8).

y - y_1 = m(x-x_1)\\y - 8 = 1(x --7)\\y - 8 = 1(x + 7)\\y - 8 = x+7
