Question

Use the diagram to find the value of the variable

Answer 1

x = 7

Explanation:

The sum of interior angles for the given rectangle can be found with the following formula:

(S-2)×180

• S is the number of the sides/angles.

There are four angles:

2×180 = 360

• Now we need to add te given measures/variables up.

15x + 5 + 98 + 10x + 6 + 76 = 360

• Add like terms.

25x + 185 = 360

• Subtract 185 from both sides.

25x = 175

• Divide both sides by 25

x = 7
