Answer:
They are supplementary
Step-by-step explanation:
Since AB and DC are parallel, then the alternate interior angles are congruent because there is transversal cutting the parallel lines (BC). So m<B is supplementary to m<C
Answer:
Just 3 simple steps!!
Step-by-step explanation:
Rule 1 : Read the the problem through until you understand it Rule 2: Find out what the problem is asking you to solve for Rule 3: Write down what is given , like variables terms, equation and write what your solving for
it would be positive because the positive number is bigger than the negative number.
Option A:
m∠B = 28°
Solution:
Given ABC is a triangle on the circle.
m∠A = 62°
<em>The angle subtended by a diameter or a semicircle on any point of circle is 90°.</em>
AB is a diameter and C is the angle subtended on a diameter.
Therefore, m∠C = 90°.
Triangle sum property:
<em>Sum of the angles of the triangle = 180°</em>
m∠A + m∠B + m∠C = 180°
62° + m∠B + 90° = 180°
m∠B + 152° = 180°
m∠B = 180° – 152°
m∠B = 28°
The measure of angle B is 28°.
Hence Option A is the correct answer.
