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
⇒∠1 = ∠3 = 130
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
Answer:

Step-by-step explanation:
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)


(x - 6)(x - 4) = 0
x - 6 = 0 .... x - 4 = 0
x = 6 .... x = 4
4 or 6
