Question

what is the measure of angle B

Answer 1

The Measure of angle B is [180°-(∠A+∠C)°]°.

• A triangle is defined as a polygon with three vertices and three edges. We know the sum of the total 3 angles is 180°. This means if three angles are A, B, and C then we can say ∠A+∠B+∠C=180°.So, ∠B = 180°-(∠A+∠C)°.
• The angle can be measured in radians or degree.

Answer 2

Answer:

The Measure of angle B is $180^{0} -($∠$A^{0} +$∠$C^{0} )$

Step-by-step explanation:

A triangle is a three-sided polygon with three vertices. The triangle's internal angle, which is $180$ degrees, is constructed. It implies that the internal angles of a triangle add up to 180 degrees. It is the polygon with the fewest sides. Or to put it another way, a triangle is a three-sided, two-dimensional shape whose internal angles are $180^{0}$.

• A triangle is defined as a polygon with three vertices and three edges. We know the sum of the total 3 angles is 180°. This means if three angles are A, B, and C then we can say ∠A+∠B+∠C=180°.So, ∠B = 180°-(∠A+∠C)°.
• Angles can be calculated using degrees or radians.
