Pllllleeeaaasssssssseeeee help me with this math fast!
a. Find x. The figure is not drawn to scale.
b. Is the triangle equilateral, isosceles, or scalene? Explain.

surely you know that the circle contains 360°. So,

(8x-10) + (6x) + (10x+10) = 360
x = 15
Answered by hi
what about the triangle thing ????????
Answered by _-_
a. Since the measure of all of the arcs in a circle equal 360°, so we can use the equation (8x-10) + (6x) + (10x+10) = 360 to solve.
(8x-10) + (6x) + (10x+10) = 360
we combine like terms, and since the tens cancel out,
24x=360
/24 /24
x=15
b. Since we know x, we can see what triangle this is because Theorem 12-6 states congruent chords have congruent arcs. With this in mind, we can see if
any sides are congruent by solving their corresponding arcs.
8(15)-10= 110
6(15)= 90
10(15)+10= 160
Since none of the arcs are congruent, none of the cords are congruent. Therefore, the triangle is scalene.

Thank you Steve!

im confused on how you guys solved for x
Answered by qqq
are the above correct?
Answered by to anony
How they found the answer is first they solved (8x-10) + (6x) + (10x+10) which equals 24x = 360, divide 360/24, then you have x=15

Yes, that is correct. They combined the arc measures of the three arcs, set it equal to the measure of the entire circle (which is 360 degrees), and solved for x.
