Question

Find the value of x 90, 2x, and x

Answer 1

The sum of the acute angles in a right triangle is 90°.

Therefore we have the equation:

x° + 2x° = 90°

3x° = 90°     divide both sides by 3

x° = 30°

Answer: x = 30

Answer 2

2x = 60°
x = 30°

To solve this, you subtract 90° (thevright angle) from 180° (all triangles have 180°). This means that the total of 2x and x is 90°.

Because there are 3 x's in total, we get
$3x = 90$
which can be simplified to
$x = 30$
by dividing both sides by 3.

This means that x=30°, and then multiplying x by 2 to get 2x=60°.
