The measure of angle ACB for circle centered at point O is 21°

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

∠AOB = 2 * ∠ACB (angle at center is twice the angle at circumference)

42 = 2 * ∠ACB

∠ACB = 21°

The measure of angle ACB for circle centered at point O is 21°

I’m not sure how to do this.. can anyone help?

Answer:

m<1 =95

m<2 = 130

Step-by-step explanation:

I take it you want the size of <1 and <2?

<ABC + 95 = 180       Same straight line.

<ABC = 180 - 95        Subtract 95 from both sides.

<ABC = 85                  Combine

===========================

<1 + <ABC = 180          Interior angles on the same side of the transversal = 180

<1 + 85 = 180

<1  = 180 - 85

<1 = 95

=============================

Givens

<ABC = 85

m< 1  = 95

<ADC = 50  Given

m<2 = ?

m<2 + <ABC + m<1 + 50 = 360     The four angles of a quadrilateral add to 360

m<2 + 85  + 95 + 50 = 360      

m<2 + 230 = 360

m<2 = 360 - 230

m<2 = 130
