WebApr 3, 2024 · Also, we know that in a circle angle subtended by a chord on the same arc of a circle are equal. Hence, from the figure we see that $ \angle BAC\,\,and\,\,\angle BDC $ are angles subtended by chord BC on the arc of a circle. $ \therefore \angle BAC = \angle BDC $ But, the value of $ \angle BAC\,\,is\,\,{80^0}. $ Calculated above.

WebMay 2, 2024 · We can fill the above information into our diagram. Since ∠ADB and ∠BDC are supplementary, their total degree measurement is equal to 180. Thus, m∠ADB = 180 – 60 = 120 degrees. Since we have 2 of the 3 angles in triangle ABD, we can determine the measure of ∠BAC: m∠BAC = 180 – 120 – 20 = 40 degrees. WebAngle BAC is an inscribed angle, which means that its meausre is one-half of the measure of the arc that it incercepts, which is arc BC. Thus, since angle BAC is 35 degrees, the measure of arc BC must be 70 degrees. We can use a similar strategy to find the measure of arc CD, which is the arc intercepted by the inscribed angle FBD.
