Answer this besties The triangle ABC above shows the angle of elevation of the top, B, of a tower, BC, from A, to be 30°. AB=40 m. The length of BC is​

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
