Which expression is equivalent to (3x2-7
(2x - 11)-(x2+4)
(522-6)-(2x2-1)
(10x2-4)-(7x+3)
(15x2 +8)= (18x2 +1)

∠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°

its 4 because 2 times 2 is 4, if you double the number two you get four

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

the answer is 13 cm
