Find the value of y. <br> Answer options: 62, 66, 70, 74
Pie

Answer:

The value of y = 70°

Step-by-step explanation:

∵ The measure of the major arc = 160 + 60 = 220°

∵ The measure of the circle is 360°

∴ The measure of the minor arc = 360 - 220 = 140°

∵ y is the angle between a chord and a tangent

∵ The chord subtended by the arc of measure 140°

∵ y is subtended by the arc of measure 140°

∵ Angle of tangent subtended by an arc,

  its measure = half the measure of the subtended arc

∴ The measure of y = 1/2 the measure of the subtended arc

∴ y = 1/2 × 140 = 70°

Evaluate the following expression. 70
vovikov84 [41]
I am assuming the -3 is an exponent.

y⁻³ and 5⁻³

If the exponent is a negative number, it simply means that the number is a denominator with 1 as the numerator.

y⁻³ is 1/y³
5⁻³ is 1/5³ = 1/125

The number is still raised to its exponential power but its placement is different.

5³ would be 125 or 125/1. It would be the numerator with 1 as the denominator.
