I believe its 80 if you derive it out, but there is no units of measurement.

Answer:

x=5

Step-by-step explanation:

<u>Similar Triangles</u>

By looking at the construction of the figure, we can safely assume both triangles are similar, i.e. their internal angles are equal and their sides are proportional. Following the proportion of the heights and bases of both triangles we can set this relationship:

\displaystyle \frac{45}{36}=\frac{5x}{20}

Simplifying both fractions

\displaystyle \frac{5}{4}=\frac{x}{4}

Solving for x

x=5

Find the unknown angle measures
Usimov [2.4K]

Answer:

Step-by-step explanation:

ok so this is a vetical angle. so they are equal to 180. so if 1 measurement is found the other is the difference of 180 and that angle measeurement.

so y is the same as 110

and 180 - 110 is 70, so x and z are equal to 70.

i hope this helped you :)

Answer:

50 combos

Step-by-step explanation:

Put it into an equation first in order to find x.

2x + 250 = 7x

Subtract 2x from both sides.

250 = 5x

Then divide both sides by 5.

x = 50

Therefore you need 50 combo meals in order to make the amount made equal to the amount paid.

<u>You can check your work by plugging in the number to both.</u>

$250 plus the $2 times 50 combo meals.

250 + 2(50) = 350

$7 times 50 combo meals

7 x 300 = 350
