Evaluate the function f(x)=1−x/−4+x at the indicated values: f(a-1)= Note: Ignore the format of how I have it typed in the box you have to do it a certain way. Just put the answer in the regular written form.

∠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°

you need to add a picture

step-by-step explanation:

there's the chart

substitute,

circle 1 = 5

circle 2 = 20

circle 3 = 44

in this case no matter how you add, you will always get a perfect square..

hence proved
