Answer:
46°
Step-by-step explanation:
When secants intersect each other and a circle, the external angle (A) is half the difference of the intercepted arcs:
∠A = (arcDC -arcBC)/2
12° = (arcDC -22°)/2 . . . . . . . fill in the given numbers
24° = arcDC -22° . . . . . . . . . multiply by 2
46° = arcDC . . . . . . . . . . . . . add 22°
3.06% becomes 0.0306 as a decimal, then you make it
306/10000
Simplify that:
153/5000
Hope this helped!
Sides are x,x,b
x is identical side
x is bigger than 3 times b by 2
x=3b+2
p=x+x+b
60=2x+b
x=3b+2
60=2(3b+2)+b
60=6b+4+b
60=7b+4
minus 4 both sides
56=7b
divide both sides by 7
8=b
sub back
x=3b+2
x=3(8)+2
x=24+2
x=26
legnths are
26in, 26in, 8in
