What is the measure of angle B?

Enter your answer in the box.

m∠B=
°

A quadrilateral inscribed in a circle. The vertices of the quadrilateral lie on the edge of the circle and are labeled as A, B, C, D. The interior angle B is labeled as left parenthesis 3 x minus 12 right parenthesis degrees. The angle D is labeled as x degrees.

The measure of angle B is 132°

Explanation:

Given that the quadrilateral is inscribed in a circle.

The vertices A, B, C, D of a quadrilateral lie on the edge of the circle.

The angle B is given by

The angle D is given by

We need to find the measure of angle B.

Since, the angles B and D are opposite angles.

Also, we know that the opposite angles of a quadrilateral are supplementary.

Thus, we have,

Substituting the values, we get,

Thus, the value of x is 48

Substituting the value of x in the angle B, we get,

Thus, the measure of angle B is

132

Step-by-step explanation: Just confirming the answer :)

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.
