Answer:

A and D

Step-by-step explanation:

Since tangent is opposite/adjacent,

Tan 40 in this case would be x/3.8 (i used x because we don't know what the value is)

So, you set it up as an algebra problem

Tan40 = x/3.8

Multiply both sides by 3.8

3.8tan40 = x, Option A

And then, angle E is 50 degrees

So tan 50 = 3.8/x

Multiply both sides by x

tan50x = 3.8

Divide both sides by tan50

x= 3.8/tan50

So, A and D are both correct

P(F) = 0.5
P(L) = 0.3
P(F\cap L)=0.2
P(F\cap L')=0.5-0.2=0.3
P(F'\cap L)=0.3-0.2=0.1
P(F'\cap L')=1-0.3-0.2-0.1=0.4

Alex and Peter win some money and share it in the ratio 3:5. Alex gets £33. How much did Peter get?
IgorLugansk [536]

Answer:

Step-by-step explanation:

Set it up as fractions, Alex over Peter.

3/5 : 33/x  Let x represent Peter's amount.  Now find out: how do you get from 3 to 33?  What times 3 equals 33?  11

What you do on the top, you must do on the bottom.  If 3 times 11 equals 33, then 5 times 11 equals x.  5 times 11 equals 55, so x equals 55.

Peter will get 55.  Don't forget the pound symbol.
