Find the value of f, correct to two decimal places.

tan26=f/4 --> f= (tan26)* 4

Step-by-step explanation:

Put (tan26) times 4 into calculator

SOH, CAH, TOA rules!!

sin(x)=opposite/hypotenuse

cos(x)=adjacent/hypotenuse

tangent(x)=opposite/adjacent

DON'T PUT 90 FOR THE (x) VALUE!!

** (x) here means the angle given to you in the question like 26 in this case.

** opposite and adjacent are the sides according to the angle

**hypotenuse is the opposite side of the right angle

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
