ivann1987 [24]

Answer:

Step-by-step explanation:

Supplementary angles add up to 180

∠1 + 50 = 180

∠1 = 180 - 50

∠1 = 130

∠3 +50 = 180   {Supplementary}

∠3 = 180 - 50

∠3 =130

△ABC has a>b>c. If one of the angles in the triangle is 60°, name the angle that can be equal to 90°.
Aleksandr-060686 [28]

Answer:

Angle A

Step-by-step explanation:

a is greater than b, which is greater than c

a triangle has 180 degrees

so 180-90 is 90

90-60 is 30

a>b>c

90>60>30

this would be a right triangle since one of the angles is 90 degrees

Special segments in circles
pochemuha
If two chords intersect in a circle, then the products of the measures of the segments of the chords are equal.
I'm assuming that number up top is an 8. It's kind of blurry.

Since ten is a chord, and x is a segment of it, it can be expressed as x and 10 - x.
3(8) = x(10 - x)
24 = 10x -  x^{2}
x^{2}  - 10x + 24 = 0
(x - 6)(x - 4) = 0
x - 6 = 0     ....       x - 4 = 0
x = 6           ....       x = 4

4 or 6
