If segment ac and segment bc are tangent to circle o find the value of x

Mathematics
1 answer:
Monica [59]3 years ago

Answer:

x = 130°

Step-by-step explanation:

At the points of Tangency, A and B, the angle formed are equal to 90° based on the tangent theorem.

Therefore, m<A and m<B both have a degree measure of 90° each.

Thus, the sum of the interior angles of quadrilateral AOBC = 360° (sum of interior angles of a quadrilateral).

Therefore:

x + m<A + m<B + m<C = 360°

x + 90 + 90 + 50 = 360 (substitution)

x + 230 = 360

x = 360 - 230 (subtraction property of equality)

x = 130°

As a reward for being name employee of the year Janice will receive a 3.5 pay raise . If Janice new salary is 45,000 how much wa
satela [25.4K]

Answer:

Salary before pay raise = 43,478.26 (approx)

Step-by-step explanation:

Given that:

Janice new salary = 45,000

Pay raise = 3.5% = 0.035

Let the previous pay be x

Now according to given conditions:

0.035* x = 45,000 - x

Adding x on both sides we get:

0.035 x + x =  45,000 - x + x

1.035x =  45,000

Dividing both sides by 1.035 we get:

1.035/1.035 x =  45,000/1.035

x = 43,478.26

So, the salary before pay raise was 43,478 approx

proof:

Raise in salart = 3.5% of 43,478.26 = 1,521.74

New salary = old salary + raise in salary

New salary = 43,478.26 + 1,521.74

New salary = 45,000

Hence proved.

I hope it will help you!
