Answer:

A circle measures 360 degrees, so a semicircle measures 180 degrees. By using the inscribed angle theorem, the measure of the inscribed angle would be half of 180 degrees, or 90 degrees, which is a right angle.

Step-by-step explanation:

Answer:

The angle inscribed in a semicircle is a right angle. The inscribed angle theorem states that the angle θ, inscribed in a circle is half the measure of the central angle of the circle. So, if the given is a semi-circle, then the inscribed angle is half of 180, therefore, 90 degrees and a right angle

Convert the angle measure 40° to a radian measure?

Sophie [7]

Answer:

The answer is

Step-by-step explanation:

To convert an angle from degrees to radians multiply the value by $\frac{\pi}{180}$ .

From the question the value is 40°

It's equivalent in radians is

$40 \times \frac{\pi}{180} = \frac{40\pi}{18 0} = \frac{2\pi}{9} \\$

We have the final answer as

$\frac{2\pi}{9} \\$

Triangle ABC is represented by the drawing below.

zhannawk [14.2K]

Step-by-step explanation:

Therefore,

(x+20) + (x-10) + (2x-30) = 180° (Sum of interior angles of a triangle)

Or, x+x+2x+20-10-30 = 180°

Or, 4x-20 = 180°

Or, 4x= 180+20

Or, 4x= 200°

Or, x= 200°/4

Therefore, x= 50°

So,

(x+20)

= 50+20

=70°

(x-10)

= 50-10

40°

(2x-30)

= 2×50-30

=100-30

=70°

Carl ran around the track 3 more times than Daria and 2 fewer times than Erin. When they were done they added up the number of l

Paul [167]

Answer:

Total laps = 10d

Step-by-step explanation:

Let c = Carl's laps

d = Daria's laps

e = Erin's laps

c = 3d

c = e/2

c + d + e = totals laps

We can insert 3d in place of c in the third equation

3d + d + e = total laps

Also, e/2 equals 3d

e/2 = 3d

Multiply both sides by 2

(e/2 = 3d)2

e = 6d

Insert the new e

3d + d + 6d = 10d = totals laps
