Answer:

Step-by-step explanation:
Answer:
90
Step-by-step explanation:
The angle formed outside = 1/2(difference of intercepted arcs)
The large arc is 360-x and the inner arc is x
x = 1/2 (360 -x - x)
x = 1/2 (360 -2x)
Multiply each side by 2
2x = 360 -2x
Add 2x to each side
2x+2x = 360
4x= 360
Divide by 4
4x/4 = 360/4
x = 90
Any number 1.44 and lower is possible. i dont know too many details, but given this i can figure some out.
Answer:
Step-by-step explanation:
x^2 + 4x = 15.....take half of ur x term, then square it, then add to both sides
x^2 + 4x + 4 = 15 + 4
(x + 2)^2 = 19
sqrt (x + 2)^2 = sqrt 19
x + 2 = sqrt 19
x = -2 (+ - ) sqrt 19
so x = -2 + sqrt 19 or x = -2 - sqrt 19
