Answer: X=87


Step-by-step explanation: First and foremost, all triangles add up to 180 degrees, remember that.

In order to find this answer you need to set up an equation, we know all triangles add up to 180, now we just solve for X by plugging in a few numbers.

38+ 55+ X = 180

<em>Add</em> 38 and 55 to get 93.

93 + X = 180

Now bring 93 to the other side of your = using <em>subtraction</em>.

93 + X = 180 - 93

Now you can<em> cancel out  </em>your 93, and do the math on the right side of the equation.

You're left with <u>X= 87.</u>

*If you want to check your answer you can do 38+55+87 and it should equal 180 because all triangles add up to 180.

Hope this helped!!

Find the value of the variable. If your answer is not an integer, leave it in simplest radical form.
AlekseyPX

Answer:

$\frac{5\sqrt{2} }{2}$

Step-by-step explanation:

x: \text{opposite side of the angle of 45\º}

5: \text{hypotenuse of the right triangle}

$\sin(\theta)=\frac{\text{opp}}{\text{hyp}} \Rightarrow \sin(45\º)=\frac{x}{5} $

$\text{Once }\sin(45\º)=\frac{\sqrt{2} }{2} $

$\frac{\sqrt{2} }{2} =\frac{x}{5} \Rightarrow 2x=5\sqrt{2} \Rightarrow x=\frac{5\sqrt{2} }{2}  $

You can just remember that 5 is the diagonal of a square of side length x.

$5=x\sqrt{2} \Rightarrow x=\frac{5}{\sqrt{2} } \Rightarrow x=\frac{5}{\sqrt{2} } \cdot \frac{\sqrt{2} }{\sqrt{2} } = \frac{5\sqrt{2} }{2} $
