Answer:
The following triangle is equilateral triangle. Solve for the
unknown variable. y=17 is the answer
I think the correct answer among the choices listed above is option C. Alexa is constructing a circle inscribed in a triangle. She has partially completed the construction. Her next step is to use the arc markings to determine the radius to construct the circle.
Answer:
a ≈ 8.9
Step-by-step explanation:
Set up the equation as so:
8a^2 + 2 = 634
First, subtract two from both sides:
8a^2 = 632
Then, divide by 8 to further isolate the variable.
a^2 = 79
To get rid of the squared, you have to take the square root of both sides. The square root of 79 is roughly 8.9. Ergo, a ≈ 8.9
