7^2+4^2/2^5
thx anyone who answers

7²+4²/

49 +4²/

49+16/32

16/32 = 1/2

1/2 + 49 = 99/2 or 49.5

step-by-step explanation:

see if this :

∠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°
