A circle is inscribed in a 40º-60º-80º triangle. The points of
Vladimir [108]

Answer:

A = 50°

B = 60°

C = 70°

Step-by-step explanation:

If we draw a line from each vertex through the center of the circle, we perpendicularly bisect the line joining the adjacent tangent points.

We then know the original angle is halved and the remaining angle of each right triangle is complementary to half the original.

Now we can subtract the known angles along each line of the original side to find the remaining angle

Does a = 8 b=15 c=17 make a right triangle and why​
ArbitrLikvidat [17]
Ok so pythagorean theorem is
a^2+b^2=c^2
plug it in
8^2+15^2=17^2
64+225=289
289=289

yass it works so that means they do make a right triangle

yes, they make a right triangle because they're a pythagorean triple and pythagorean theorem works when you plug the numbers in.

How do you solve the math equation
GalinKa [24]
First of its y-y1 = m(x-x1)
m is the slope, what it is increasing by. 
y1 is the y intercept of your pair. 
X1 is the x intercept of your coordinate pair, plug them in. If you dont know slope the formula to find it is:
y2-y1/x2-x1
