Why is it reasonable to use the same units to describe circles and measure of angles?

Mathematics
1 answer:
Oxana [17]3 years ago
5 0

Answer:

<u><em>The more familiar unit of measurement is that of degrees. A circle is divided into 360 equal degrees, so that a right angle is 90°.</em></u>

Explanation:

The unit circle, or trig circle as it's also known, is useful to know because it lets us easily calculate the cosine, sine, and tangent of any angle between 0° and 360° (or 0 and 2π radians)

Guys I really need help plsss
timama [110]

Answer:

x = 3

Step-by-step explanation:

Multiply the first equation by -1, then add it to second equation.

 2x+9y = -12

-2x-7y = 8

-------------------

 2y = -4

Solve for y

2y = -4

y = -2

Plug value of y into one of the equations and solve for x

2x + 9(-2) = -12

2x  = 6

x = 3

Find the volume of the following solid:
goblinko [34]

Answer:

93214.28 cm³

Step-by-step explanation:

The area of the given solid in the front side is = area of the rectangle + area of the semi circle.

= ( 40 × 30 ) + 0.5 × π × r²

= (40 \times 30) + 0.5 \times  \frac{22}{7} \times 15^{2} {Since radius = 0.5 × Diameter = 0.5 × 30 = 15 cm}

= 1553.57 cm².

Now the volume of the solid is given by (Area of the vertical surface × horizontal length) = 1553.57 × 60 = 93214.28 cm³ (Answer)

I need help with geometry
Ede4ka [16]

Answer:

corresponding angles

the angles are equal

equation: 9x+8 = 4x+18

x=2

angle measurements: 26⁰

Step-by-step explanation:

solve your equation

9x+8 = 4x+18

subtract 4x from each side

5x + 8 = 18

subtract 8 from each side

5x = 10

divide by 5

x = 2

insert x=2 into original equations to make sure you get the same answer.

9(2) + 8 = 26

4(2) + 18 = 26
