Answer:

90°,60°&30°

Step-by-step explanation:

A 30-60-90 triangle is a right triangle with angle measures of 30º, 60º, and 90º (the right angle). Because the angles are always in that ratio, the sides are also always in the same ratio to each other.

Help me find the X please !! Thank youu

Elenna [48]

We can use the vertical angle theorem which states that any two opposite angles are congruent. So, you can just set the two measures equal to each other and solve for x:
$7x-99=2x+1$
$5x-99=1$
$5x=100$
$x = \frac{100}{5} = 20$

So, your answer is 20°.
