Determine the value of y. 1)

46°

2)

226°

3)

132°

4)

452°

y = 46

Step-by-step explanation:

Angle Formed by Two Tangents= 1/2(difference of Intercepted Arcs)

We can find the other arc by the total arc of a circle minus the arc length 226

y = 1/2 ( 226 - ( 360 -226))

y = 1/2 ( 226 -134)

y = 1/2 (92)

y = 46

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
