Answer:
b = 180°-23°
= 157°
c = 23°
Explanation:
For b, we have to use the Supplementary Angles property of intersecting lines . Supplementary angles are formed when two lines intersect each other, and the two adjacent angles then formed are termed as supplementary angles. Also, the sum of any pair of adjacent angles formed by intersecting lines is 180 degrees.
One angle of a pair will always be given to you, so you just have to subtract that angle from 180, then you will get the other angle as well.
For c, We must employ a straightforward property known as the Vertically opposite angle property. And the property states that verically opposite angles are equal. When two lines intersect, 4 angles are formed. You will notice that two angles are just opposite to each other. In the given image, angle c is just opposite to 23° angle. So angle c will sames as its vertically opposite angle.
