Answer:
A = 22.62
Step-by-step explanation:
Remember law of tan
tan = opposite/adjacent
tan (A) = 5/12
A= tan inverse ( 5/12)
A = 22.62
You put the whole number over 1 then multiply so both fractions have the same denominator.
Example:
2- 1/2
2/1 -1/2
4/2 - 1/2 = 3/2 = 1 1/2
I’m not sure if this helped but I hope it did
Answer:
Step-by-step explanation:
2k+10 | Both terms share the common factor two, so you can take it out (divide both terms by 2)
2(k+5) | Now if you use the Distributive Property to double check, you get 2k+ 10 again
Step-by-step explanation:
(a)
ii.
21 - 5 = 16 play only chess.
iii.
23 - 5 = 18 play only cards
5 play both.
that is 16+18+5 = 39 that play at least one of these games.
i.
so, 45 - 39 = 6 don't play any of these games.
(b)
we have 16+18 = 34 pupils out of 45 that play exactly one game.
so the probabilty to pick one of them is as usual
desired cases / total cases = 34/45 =
= 0.755555555... ≈ 0.76
A)106°- angle at the centre is half of the angle at the circumference
b)74°- when a tangent meets a radius a right angle is created(90+90+106)= 286 360-286= 74°
