Question

3. Find the values of x and y given this diagram​

Answer 1

Explanation:

5y and 45 are supplementary. They add to 180 degrees.

5y + 45 = 180 Subtract 45 from both sides.

-45 -45

5y = 135 Divide by 5

/5 /5

y = 27

2x+ 1 and 45 are vertically opposite which means they are equal.

2x+1 = 45 Subtract 1 from both sides

2x + 1 -1 = 45-1

2x = 44 Divide by 2

/2 /2

x = 22

Answer

• x = 22
• y = 27
