Answer:
b = 55°
Step-by-step explanation:
The angle at the centre is twice the angle on the circle subtended by the same arc, then
a = 0.5 × 110° = 55°
Angles on the circumference subtended by the same arc are congruent, so
b = a = 55°
For this case, the first thing we must do is the composition of functions.
We have:
f (x) = x ^ 2- (1 / 2x) +4
g (x) = 8x-2
(gOf) (x) = 8 (x ^ 2- (1 / 2x) +4) -2
We rewrite: now the function:
(gOf) (x) = 8x ^ 2- (8/2) x + 32-2
(gOf) (x) = 8x ^ 2-4x + 30
Answer:
The final result is:
(gOf) (x) = 8x ^ 2-4x + 30
Answer:
40
Step-by-step explanation:
why ? because the total angle measure in triangle is 180degree so we have a right angled triangle so 90+50 = 140
180-140 = 40
hope it's correct
