Answer:

82.4 cm

Step-by-step explanation:

The computation of the height is given below:

As we know that each right triangle contains the top angle of 20 degrees

So, the right angle & the bottom corner angle equivalent to

= 180 - 90 - 20

= 70 degrees

Now the height is

tangent = opposite leg ÷ adjacent leg

tan (70°) = height ÷ 30 cm

height = 30 cm × tan (70°)

= 82.4 cm

Lilit [14]
210 grams into ounces
210 / x = 28.4 / 1

If bob makes 40 mintues of long distance call for the month, which plan cost more
lora16 [44]

First, look at the x axis (this is the one labeled Minutes Used per month)

Find the number 40, then look at where the lines meet on that line. The red line for Plan B it’s at 8 dollars. The blue line for Plan A is at 4 dollars.

Plan B costs more.

To find the difference, subtract 4 from 8.

$8 - $4 = $4

Plan B costs 4 dollars more than Plan A.

If you have any further questions feel free to ask.

Hope this helps.
