All angles in a triangle add to 180 so B is
B = 180 - 90 - A
B = 90 - 35.3
B = 54.7°
Can find a with sine of A
sin(A) = a / c
a = c sin(A)
a = 4.1 sin(35.3)
a = 2.37 mm
Can find b with cosine of a
cos(A) = b / c
b = c cos(A)
b = 4.1 cos(35.3)
b = 3.35 mm
B = 54.7°, a = 2.37 mm, b = 3.35 mm
It’s the third choice because the highest degree is three and there are three terms. FOR QUESTION 3
The first two choices for QUESTION 4
Answer:
wouldn't it be the first one
but im not good at math
Step-by-step explanation:
like its showing you have of the whole so the other part must be the same
Answer:
£2598.80
Step-by-step explanation:
155 people pay
49 are under 16
The number of 16+ people is: 155 - 49 = 106
Total money collected:
106 * £18.60 + 49 * £12.80 = £1971.60 + £627.20 = £2598.80
