Angle A is circumscribed about circle O. What is the measure of D?

Mathematics

Mariana [72]3 years ago

Answer:

m<D=50

Step-by-step explanation:

The reason is that ABOC is a quadrilateral, so its angle add up to 360*. Each of the tangent angles, <ABO and <ACO, has a measure of 90*.

m<ABO + m<ACO + m<A + m<O = 360

90 + 90 + m<A + m<O = 360

m<A + m<O = 180

80 + m<O =180

m<O = 100

If the measure of central angle <O is 100*, what is the measure of inscribed <D?

The measure of a central angle is equal to the measure of the arc it intercepts. If m<O = 100*, then m BC = 100.

The measure of an inscribed angle is half of the measure of the arc it intercepts. If m BC = 100*, then m<D = 50

m<D=50

Find x. Leave answers in simplified radical form. (Step by step)
just olya [345]

Answer:

\sf x  = 4\sqrt{2}

Given:

  • adjacent: 4 cm
  • hypotenuse: x cm
  • angle: 45°

<u>using cosine rule:</u>

\sf cos(x)  = \dfrac{adjacent}{hypotenuse}

\sf cos(45)  = \dfrac{4}{x}

\sf x  = \dfrac{4}{cos(45)}

\sf x  = 4\sqrt{2}

Solve for x: 2+3 (x+2x) = -2x(2-4) +1
Ronch [10]

Answer:

x = -1/5

Step-by-step explanation:

2+3 (x+2x) = -2x(2-4) +1

Combine like terms

2+3(3x) = -2x (-2) +1

Distribute

2+9x = 4x +1

Subtract 4x from each side

2+9x-4x = 4x+1-4x

2+5x = 1

Subtract 2 from each sdie

5x = 1-2

5x = -1

Divide by 5

5x/5 = -1/5

x = -1/5

Two sides of a triangle have lengths 6 and 17. Which expression describes the length of the third side?
VashaNatasha [74]
The answer is D which is greater than 11 and less than 23. 
<span>Sum of 2 sides of triangle is always greater than the third side. And absolute difference of 2 sides of a triangle is always less than the 3rd side. From that, 3rd side ia less than 6+17 = 23 and greater than 17-6=11.</span>
