Answer:
Step-by-step explanation:
All the angles in a triangle have to add up to 180 degrees.
#17.)
45+50=95
180-95=85
x=85
#18.)
This one is a little different. The furthest two angles are complimentary which means that they add up to 180 degrees (a straight line.) Once you find the missing angle to that one, you can do the same thing as you did in #17.
180-118=62.
25+62=87
180-87=93
x=93
#21.)
For this one a slightly larger equation is needed. Since we don't have a definite number for the bottom left angle, we have to use x+2 as our number. We first have to find the bottom right angle though.
180-108=72
x+x+2+72=180
2x+74=180
2x=106
x=53

I got -6, I hope this helps
Let us consider that Christopher is 'x' years old
Age of Christopher = x
George is 8 years more than Christopher
Age of George = (x + 8)
Ford is 2 years younger than Christopher
Age of Ford = (x - 2)
Now the sum of their ages is 60
∴ x + (x + 8) + (x - 2) = 60
3x + 6 = 60
3x = 60 - 6
3x = 54
x = 54 ÷ 3
x = 18
Age of Christopher = x = 18 years
Age of George = (x + 8) = 18 + 8 = 26 years
Age of Ford = (x - 2) = 18 - 2 = 16 years
The sum of all their ages = 18 + 26 + 16 = 60 years
