Angles in a triangle always add to 180 degrees. 180=(8x+3degrees)+(10x-4 degrees)+91
180-91=89 89=(8x+3 degrees)+(10x-4 degrees) 89-3= 86 86+4=90
(8x+10x=18x) 18x=90
divide bothe sides by 18
x = 5
1. x is the number of feet, y is the number of inches
2. substitute means to replace a variable with a number
3. y = 12 (5) = 60 inches.
Answer:
