Answer:

\large\boxed{x=10}\\\\\boxed{40^o,\ 50^o,\ 90^o}

Step-by-step explanation:

We have the right triangle. The sum of the angles measured in the right triangle is 90 °. Therefore we have the equation:

4x+(6x-10)=90[/tex][tex]4x+6x-10=90  <em>                 add 10 to both sides</em>

10x=100           <em>divide both sides by 10</em>

x=10

The measure of angles:

Put the value of x to the eqpressions:

6x-10\to6(10)-10=60-10=50\\\\4x\to4(10)=40

Math help please? There are 12 more toy cars than toy trucks in a box with a total of 38 toy cars and toy trucks. How many toy t
dlinn [17]
Let, the number of toy trucks = x
Then, number of toy cars = (x + 12)

Now, we have: x + x+12 = 38
2x + 12 = 38
2x = 38 - 12
2x = 26
x = 26/2
x = 13

So, there are 13 toy trucks in total.

Hope this helps!

prisoha [69]
To answer the question above, divide the total amount raised (T) during fundraising by the number of future exhibits (n). The amount of money (m) each exhibit will receive, 
                                  m = T / n = ($1664) / 8 = $208
Thus, each exhibit will receive $208.
