Answer:

Step-by-step explanation:

∠A + ∠B = 90    {∠A & ∠B are complementary}

x + 16 + x - 12 = 90

x + x + 16 - 12 = 90       {Combine like terms}

2x  + 4 = 90        { Subtract 4 form both sides}

        2x = 90 - 4

        2x = 86          {divide both sides by 2

        x   = 86/2

           x = 43

A scientist who studies sleep has developed a new technique to help people sleep each night. He
Andru [333]

Considering the situation described, the scientist's null and alternative hypothesis are described by:

Null hypothesis H_0: \mu = 0; Alternative hypothesis H_1: \mu \neq 0.

<h3>What are the hypothesis tested?</h3>

At the null hypothesis, it is tested if there is no difference, that is, the difference of the means represented by \mu is of 0, hence:

H_0: \mu = 0

At the alternative hypothesis, it is tested if there is a difference, hence:

H_1: \mu \neq 0

Given: circle k(O) m∠R = (12x+1)mFP = (11x+7) mPQ= 60Find: mFP
zhannawk [14.2K]

Answer:

62°

Step-by-step explanation:

The angle R inscribes the arc FQ, so using the property of inscribed angles in a circle, we have that:

m∠R = mFQ / 2

The arc FQ is the sum of the arcs FP and PQ, so we have:

mFQ = mFP + mPQ = 11x + 7 + 60 = 11x + 67

Now, with the first equation, we have:

12x + 1 = (11x + 67) / 2

24x + 2 = 11x + 67

13x = 65

x = 5°

So we have that mFP = 11x + 7 = 55 + 7 = 62°
