The area of a triangle can be found using the formula 1/2bh, where the variable b represents the value of the base and the variable h represents the value of the height.

bearhunter [10]

The 2x and 76 are opposite angles so they are equal.

2x = 76

x = 38 degrees

y and 76  are adjacent angles so y = 180 - 76

= 104 degrees

lisabon 2012 [21]

Answer:

For the temperature to be below 32 F, following inequality must be met,

h\geq 9.333

Step-by-step explanation:

Let "t" be the temperature at any time.

General format of a linear equation can be given as,

y= mx + c

Where,

y ⇒ dependent variable ( in this case temperature t)

m⇒ Gradient ( the rate at which the temperature drops)

x⇒ independent variable ( hours )

c⇒ intercept ( this is the starting temperature)

Now we can substitute the given values to the above format to arrive at the equation,

t=-3h+60

We can re-arrange the equations as ,

3h=60-t

=h=20-\frac{t}{3}

We can write this as an inequality when t = 32 F

h\geq 20-\frac{32}{3}

=h\geq \frac{28}{3}

=h\geq 9.333
