Step-by-step explanation:
:>
His present age is 13 years.
<h3>How to solve words problems ?</h3>
The words problem can be solved as follows:
let
his present age = x
Therefore,
3(x + 5) = 54
Hence,
3(x + 5) = 54
3x + 15 = 54
subtract 15 from both sides
3x + 15 - 15 = 54 - 15
3x = 39
divide both sides by 3
3x / 3 = 39 / 3
x = 13

Answer:
1. sine = opposite / hypotenuse = 30 / 34 = 15 / 17
cosine = adjacent / hypotenuse = 16 / 34 = 8 / 17
tangent = opposite / adjacent = 30 / 16 = 15 / 8
2. you have to use the law of sines function
the formula for law of sines is
sin of angle A / side A = sin of angle B / side B = sine of angle C / side C
The information we know is sin of a and side a which is 90 degrees and side A length of 20
we don't know Side B and C
we know sin of angle B = 45 degrees
all we have to do is ratios
now divide both sides by sin(90
left side both cancel and on right side 14.14/ sin(90 = 14.14 is the answer
