A ladder 8 meters long leans against the wall of a building. if the foot of tha ladder makes an angle of 68 with the ground, how far is the base of the ladder from the wall

2.996m

Step-by-step explanation:

From the attached diagram

Let the distance = x

x = adjacent

8m = hypotenuse

Therefore we use,

Cos 68 = x/8

Multiply both sides by 8

8 × cos 68 = x

x = 8 × cos 68

x = 8× 0.3746

x = 2.996m

x is approximately 3m

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!
