This is geometry. how would I find the x pretty pls help
1 answer:
Answer:
x = 70°
Step-by-step explanation:
We are given that two of the sides are congruent so that will make the triangle isosceles.
We know also that the base angles of an isosceles triangle are congruent so we know a second angle.
< 1 = 55° ( given)
< 2 = 55° ( isosceles Δs have base <s ≅)
Using the fact that the sum of angles in a triangle is 180° we can find the third angle.
< 3 = 180 -55-55 = 70°

Answer:
(c) x plus b over 2 times a equals plus or minus the square root of the quantity b squared minus 4 times a times c all over the square root of 4 times a squared
Step-by-step explanation:
The next step is to take the square root of both sides of the equation. It can help to show the intermediate steps.
<h3>Result so far</h3>The last step shown in the derivation so far is ...
The left side of the above expression can be written as a square, and the right side can be written over one denominator. Then the square root is taken as the next step.
