Question

Find the indicated side of the
right triangle.
45°
6
45°
1
x
X = ?1

Answer 1

X is 6 because it’s a 45 45 90 triangle. X and Y are the same length and Y is whatever y is *square root of 2.

Answer 2

The value of x is 6

What is right triangle?

"It is a triangle in which one of the angle measures 90° "

What is hypotenuse?

"It is the longest side of the right triangle."

What is Pythagoras theorem?

"In a right triangle $a^{2} +b^{2}= c^{2}$ where c is the hypotenuse and a, b are other two sides of the right triangle."

What is sine angle?

"In a right triangle, sine of angle  is the ratio of the opposite side of angle  to the hypotenuse."

For given question,

For given right triangle, first we find the sine of angle 45° whose opposite side is 6 units.

$\Rightarrow sin(45)=\frac{6}{y}\\\\\Rightarrow \frac{1}{\sqrt{2} }=\frac{6}{y} \\\\\Rightarrow y=6\sqrt{2}$

Now, using Pythagoras theorem we find the value of x

$\Rightarrow x^{2} + 6^2=y^2\\\\\Rightarrow x^{2} + 36 = (6\sqrt{2} )^2\\\\\Rightarrow x^{2} + 36 = 36\times 2\\\\\Rightarrow x^{2} +36=72\\\\\Rightarrow x^{2} = 72-36\\\\\Rightarrow x^{2} = 36\\\\\Rightarrow x = 6$

Therefore, the value of x is 6
