Evaluate 3a2−5−/10−b when a=−5 and b=−3. When a=−5 and b=−3, 3a2−5−10−b=

huh. what did he sa

Step-by-step explanation:

∠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°

constants mean the stopped points or the points on a graph that nothing is changing, hope this
