<h2>Answer:</h2>

Since all angle measures in a triangle <em>MUST</em> equal 180°, we can set up an equation to solve for x.

13x + 2 + 5x - 7 + 3x - 4 = 180\\\\21x - 9 = 180\\\\21x = 189\\\\x = 9

Our answer is <em>x = 9</em>.

Klio2033 [76]
<span><span>1.       </span>There are many ways of solving this kind of division problem. But I will showing the easiest one.
15.75 divided by 0.25
=> In every 1 whole number, there are 4 of 0.25
Now we have 15 as whole number so simply multiply 15 x 4
=> 15 * 4 = 60, there are 60 pieces of .025s in 15.
=> 0.75 has 3 0.25s
Now, let’s add 60 + 3 = 63, the answer is 63.
There are 63 pieces of 0.25 in 15.75.
Let’s check
=> 15.75 / 0.25
=> 63</span>
