Answer:

55

Step-by-step explanation:

So for this you must find the unit rate at which the temperature drops in 1 hour as you are told it is constant. And so if it went down to 60 from 70 in 4 hours then 10/4= -2.5 degrees an hour. Then do 2.5 x 6 to give you that in 6 hours it shall drop 15 degrees which 70-15 gives you 55. Enjoy!

lubasha [3.4K]

Answer:

The area of triangle is $A=58.02\ ft^{2}$

Step-by-step explanation:

Let

B -----> the measure of the vertex angle of the isosceles triangle ABC

a and c -----> the two congruent sides of the isosceles triangle ABC

we know that

The area of a triangle applying the law of sines is equal to

$A=\frac{1}{2}(a)(c)sin(B)$

we have

$a=c=17.91\ ft$

$B=21.21\°$

substitute in the formula

$A=\frac{1}{2}(17.91)(17.91)sin(21.21\°)$

$A=58.02\ ft^{2}$
