Answer:

c =14.9 cm

Step-by-step explanation:

<C = 180 - (150 + 12)

<C = 180 - 162

<C = 18°

Law of sines:

sin (18) / c = sin(12) / 10

0.309 / c = 0.2079 / 10

c = 0.309 * 10 / 0.2079

c =14.9

The measure of angle D in the inscribed triangle is as follows;

∠D = 63 degrees

<h3>How to solve circle theorem?</h3>

The circle theorem can be use to find the ∠D as follows;

The triangle BCD is inscribed in the circle.

Using circle theorem,

The angle of each triangle is double the angle of the arc it create.

Therefore,

arc BC = m∠D

m∠B = 134 / 2 = 67 degrees.

Therefore, using sum of angles in a triangle.

67 + 50 + m∠D = 180

m∠D = 180 - 50 - 67

m∠D = 63 degrees.

Can anyone help me with my math homework! My teacher didn't even discuss it! I would appreciate it! Thank you!
Hatshy [7]
Please, in the future, post just one problem at a time.

Looking at Problem #1:  The line intersects the y-axis at (0,-3) and intersects the x-axis at (1,-1).  At least, this is what I see; your graph is small.
                                                                           -3-[-1]
The slope of that line is then  m = rise / run = ------------ = +2.
                                                                            0 - 1
                                       [change in y]
Slope = m = rise / run = --------------------
                                        [change in x]

Are the ratios 2.5:3.5 and 5:7 proportional? explain
yuradex [85]
\frac{2.5}{3.5}=\frac{2.5 \times 2}{3.5 \times 2}=\frac{5}{7}

They are the same fraction, so they are proportional.

4. A map has a scale of 1 inch = 100 miles. The distance between two cities is 7.25 inches. If a car travels
motikmotik

Answer:

14.5 hours/14 hours 30 minutes

Step-by-step explanation:

  • The distance between the two cities is 7.25•100=725 because you multiply the scale distance by the scale.
  • The number hours is 725/50=14.5 hours because you divide the distance by 50 (the miles per hour).
