Question

Find the value of x and y

Answer 1

Answer:

To find the value of y, you would put your expressions (12y+3, and 51 equal to each other, because they are both the same length)

12y+3=51

12y=48 (51-3=48)

y=4 (divide both sides by 12, 48/12=4)

Then to find x you want to find the missing degree of the triangle

we already know that one degree is 63 and the other is 56,

A triangle equals 180 degrees

56+63=119

Then you want to subtract 119 from 180 to find out the missing degree

180-119=61

x=61 degrees

y=4 and x=61
