Answer:
From the above attachment we can conclude that the sum of the angle 'b' and 40° is 90° (right angle)

- <u>b = 50°</u> is the right answer.
Answer: 32
Step-by-step explanation: 6 to the power of 2 is 36 plus 12 because 4 times 3 is 12 and minus 16
so 36+12-16= 32
Answers:
tan(A) = 8/15
sin(A) = 8/17
cos(A) = 15/17
==================================================
Explanation:
The tangent ratio involves the opposite over adjacent. With respect to angle A, the opposite side is 8 units long as this side is as far as possible away from angle A. In contrast, the adjacent side is 15 units long because this leg is closest possible and the two are right next to one another.
Therefore,
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = 8/15
---------------
As for the other trig ratios, they are:
sin(angle) = opposite/hypotenuse
cos(angle) = adjacent/hypotenuse
which explains why sin(A) and cos(A) are 8/17 and 15/17 respectively.
