Step-by-step explanation:
Since it's a right angled triangle we can use trigonometric ratios here.
To find FV we use cosine
cos∅ = adjacent / hypotenuse
From the question
FV is the hypotenuse
TV is the adjacent
So we have
cos 43 = TV/FV
FV = TV/ cos 43
TV =53
FV = 53/ cos 43
FV = 72.4683
We have the final answer as
FV = 72.47Hope this helps you
Ответ:
FV=72.47
Step-by-step explanation:
cos43=adj/hyp.=VT/FV
cos43=53/FV
FV=53/cos43
FV=72.46835= 72.47 rounded to the nearest hundredth

Step-by-step explanation:
4(2x+3)-5y
=8x+12-5y
Sum means addition: 2x+3
Term: Term could be a single number , variable, or the product of both. we have 8x, 12,-5y
Product ( multiplication): we have 4(2x+3), 2 multiplied by x(2x), 5y
Factor(part of a product : factor of 8x=8, x, 2 and 4
Factor of -5y=-5 and y
Factor of 12=2,4,6
Quotient ( it is the result obtained by dividing one quantity by another)= Not present in the expression. The expression doesn't have a division
Coefficient : is a number which is in product with variable.
Coefficient of 8x=8
Coefficient of -5y=-5
Coefficient of 12=12
