How many tangents do you think can be drawn from an external point to a circle? WebSep 4, 2024 · Solution. m∠A + m∠B = 180 ∘. Two supplementary angles make up a straight angle, so the measurements of the two angles will be 180 o. 48 ∘ + m∠B = 180 ∘ m∠B = 180 ∘ − 48 ∘ m∠B = 132 ∘. You know the measurement of one angle. To find the measurement of the second angle, subtract 48 o from 180 o.
