We can see from diagram that NQ is minor arc and NRQ is major arc. Our angle R (inscribed angle) and O (central angle) are corresponding to minor arc NQ. We will use inscribed angle theorem which states that measure of inscribed angle is one-half the measure of central angle.

We are given that measure of inscribed angle R is 28 degrees. To find measure of our central angle O we will multiply 28 by 2.

$28*2=56$

Therefore, measure of angle O will be 56 degrees.

Answer:

The correct answer is -7.5 years.

Step-by-step explanation:

Given:

Principle amount = 12000

Interest = 4320

time = ?

rate = 4.8 simple interest

Solution:

We know that simple Interest I = (P*t*r)/100

then t = I*100/p*r

putting values in formula:

t = 4320*100/4.8*12000

= 432000/57,600

= 7.5 years

Combine these radicals.A rectangle has an area of (x2 − 17x + 72) square units. Since the area of a rectangle is determined usin

Ilya [14]

X2 - 17x + 72

=(x - 9)(x - 8)

if x = 20 the length of the rectangle is 12 units and width 11 units.
