How to find the unknown length of right triangle

1 answer:

8 0

If you know that, you can use sin45°.
sin45°=√2/2
Because AC=18
So, the AB=9√2
And it is a right triangle, the other angle are both 45°.
So, AB=BC=9√2
Those are answer, If you don't understand you can ask me.

Answer:

x = 125

Step-by-step explanation:

Tangents from an external point to a circle are congruent , that is

CA = CB

Then Δ ABC is isosceles with base angles being congruent

∠ BAC = ∠ ABC = $\frac{180-70}{2}$ = $\frac{110}{2}$ = 55°

∠ ABC and x are adjacent angles on a straight line and sum to 180° , so

x = 180° - 55° = 125°

Then x = 125
