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

Maria and Jason are saving gas money for their trip to Boston. Maria has saved $20 more than double what Jason has. Combined Mar
valentina_108 [34]

Answer:

$60

Step-by-step explanation:

Jason saved gas money (x).  Maria saved $20 more than double what Jason has (20 + 2x).  Combined, they saved $200.  Solve for x for Jason's amount.

(x) + (20 + 2x) = 200

x + 20 + 2x = 200

3x + 20 = 200

3x + 20 = 200

3x + 20 - 20 = 200 - 20

3x = 180

3x/3 = 180/3

x = 60

Jason saved $60 for this trip.

17n + 4n- 4= 122<br><br> how do i solve for n?
Leokris [45]

Answer:

n = 6

Step-by-step explanation:

17n + 4n - 4 =122

combine like terms  17n & 4n

21n - 4 = 122

21n - 4 + 4 = 122 + 4

21n = 126

21n / 21 = 126 / 21

n = 6
