Given the angles in the trapezoid:

• 36 degrees

,

• 113 degrees

Let's find the values of a and b.

In a trapezoid, the angles on the same side of one transversal are supplementary angles and supplementary angles sum up to 180 degrees.

Hence, we have:

a° + 36° = 180°

b° + 113 = 180°

Now, let's solve for a and b.

a° + 36° = 180°

Subtract 36° from both sides:

a° + 36° - 36° = 180 - 36°

a° = 144°

b° + 113° = 180°

Subtract 113 from both sides:

b° + 113° - 113° = 180° - 113°

b = 67°

Therefore, the values of a and b are:

a = 144

b = 67

ANSWER:

• a = 144

,

• b = 67
