∠A is called inscribed angle. Inscribed angle is made from a point that attaches to the circle's circumference.

∠BOC is central angle. ∠BOC and ∠A are facing to the same side and because they are facing to the same side, they apply the rule of
inscribed angle = 1/2 × central angle

So we can find ∠A with this property
∠A = 1/2 × 132°
∠A = 66°

MakcuM [25]

If Lopez's mailing bill continues to deduct 19$ from his bank account every month for a year, then in total, the deductions total for the year would be $228.00.

Why?

$19.00 is being taken away each month. There are 12 months in a year.

$19.00 x 12 months = the total of $228.00 a year.

I think the answer is 38 degrees I just want someone to check if I am right please!

Aleksandr [31]

Answer:

JML = 142

Step-by-step explanation:

Sadly that is wrong. Not all the angles are the same. However, using the reflexive property we can find that angle JKM is 38 degrees. Using this, we need to create an equation to get the other two angles. Again, they would be the same because of the reflexive property.

38 + 38 + x + x = 360

The total needs to be 360 because the shape has 4 sides.

$76+x^{2} =360$

Now you beed to get the variable to one side. To do this you would subtract each side by 76.

$x^{2} =284$

Finally, your answer currently shows the sum of both LKJ and JML. to get one sides angle just divide by 2.

284 / 2 = 142

JML = 142

There is your answer.

Hope this helped.
