Check the picture below.
we know that AL is an angle bisector, so the angle at A gets cuts into two equal halves, we also know the angle at B is 30°, so the triangle ABC is really a 30-60-90 triangle, meaning the angle at A is really a 60° angle, cut in two halves gives us 30° and 30° as you see in the picture.
if the angles at A and B, inside the triangle ABL, are equal, twin angles are only made in an isosceles by twin sides, that means that AL = BL.
Looking at the triangle ALC, we can see is also another 30-60-90 triangle, and we can just use the 30-60-90 rule to get x=CL.
Answer:
2.236
Step-by-step explanation:
you could estimate it to be between 2 and 3 (because 5 is between 4 and 9)
or you just put it into a calculator
Answer:
x-6
Step-by-step explanation:
i believe this is correct.
One important feature of the parabola is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function.
Answer:
57 degrees
Step-by-step explanation:
Same side interior angles are supplementary which means they both equal 180 degrees.
