PEMDAS states that the value in the parenthesis should be evaluated first:
4(5*6)
4(30)
After just multiply the value in the parenthesis by the number outside of the parenthesis:

Prove: If a chord of a circle makes an angle of 30° with a diameter, prove that the distance from the center to the chord is one
Svet_ta [14]

Answer:

See explanation.

Step-by-step explanation:

Let BC be the diameter of the circle with center at point O, AB be the chord and ∠ABC=30°. OD is the distance from the center to the chord.

Consider triangle BDO. This triangle is special 30°-60°-90° right triangle. The leg OD is opposite to the angle of 30° and is half of the hypotenuse. The hypotenuse of the triangle BDO is BO. BO is the radius of the circle and is equal to half of the diameter AB. Thus,

OD=\dfrac{1}{2}BO=\dfrac{1}{2}\cdot \dfrac{1}{2}AB=\dfrac{1}{4}AB.

Step 1: Subtract 3 from both sides of the inequality.
zlopas [31]
5 - 8x < 2x + 3

5 - 8x < 2x + 3
<u>-3               - 3 </u> Step 1.
2 - 8x < 2x
<u>   +8x    +8x    </u> Step 2. Missing step
2        < 10x
<u>÷10        ÷10</u>   Step 3.
<u>2/10   < x</u>
<u>1/5     < x

The missing step is add 8x to both sides of the inequality.</u>

Answer:

The answer to your question is:

Perimeter = 26.5 units

Area = 22.5 units²

Step-by-step explanation:

Data

A (5, 9)

B (8, 0)

C (0, 9)

Formula

d = \sqrt{(x2 - x1)^{2} + (y2 - y1)^{2} }

dAB = \sqrt{(8 - 5)^{2} + (0 - 9)^{2} }

dAB = \sqrt{3^{2} + 9^{2} }

dAB = \sqrt{90}

dBC = \sqrt{(0 - 8)^{2} + (9 - 0)^{2} }

dBC = \sqrt{8^{2} + 9^{2} }

dBC = \sqrt{145}

dAC = \sqrt{(0 - 5)^{2} + (9 - 9)^{2} }

dAC = \sqrt{5^{2} + 0^{2} } \\

dAC = \sqrt{25} = 5

Perimeter = \sqrt{90} + \sqrt{145} + 5

Perimeter = 26.5 units

Area = 1/2  [ ( 5x0) + (8x9) + (0 x 9) - (5x 9) - (0x 0) - (8x9)]

        = 1/2 [ 0 + 72 + 0 - 45 - 0 - 72]

        = 1/2 [-45]

        = 45/2

        = 22.5 units²
