Answer: Presumably you are asking for the measure of a right angle in radians. That's pi/2, about 1.57079632.


Half of a pie has pi radians. A whole pie has two!! radians.


That's also the value you see on the Android calculator for cos⁻¹(0) if you tap the "deg/rad" button to pick rad. The angle whose cosine is zero is a right angle. You enter cos⁻¹(0) by swiping left, tapping inv, and then cos⁻¹, then swipe right and enter zero. Tapping deg/rad switches between 90 and 1.57079632.


Step-by-step explanation:

There are pi radians in 180°


(pi/180) radians per degree, 0.01745329


(180/pi) degrees per radian. 57.2957795

Would be 60 if pi were 3.

Answer:

w = 70°

x = 70°

y = 40°

z = 40°

Step-by-step explanation:

Notice that two sides of the figure are parallel to each other according to the arrow marking on both sides. This means that by definition this figure must be a parallelogram. This also means that the two other sides must be parallel as well so that there are also two sets of parallel sides.

There is also a transversal (line that cuts across two lines) of which are parallel, this forms different angles which are corresponding, alternate interior, alternate exterior, and supplementary.

70° at <BDC and w are alternate interior which means that they must be the same measure.

Therefore

w = 70°.

Since a parallelogram consists of 2 equal triangles, and we know that two angles are both 70° given that w is 70°, all interior angles must add up to 180° according to the triangle angle sum theorem. So 70° + 70° + y° = 180°.

140° + y° = 180°

–140° –140

Therefore

y = 40°.

Since angle x is exterior and adjacent of (next to) the two interior angles (70° and y), they are supplementary pairs which means that they add up to 180°, because they form a straight line.

Knowing that y is 40°,

x° + 40° + 70° = 180°.

x° + 110° = 180°

–110 –110

Therefore

x = 70°.

Now since angle z is alternate interior of angle y, alternate interior angles have the same measure by definition.

Given that we already know the measure of y = 40°. z must also be 40°

Therefore

z = 40°.

Clarisa's annual gross pay as an account manager is $54,000. If the graduated state tax rate is 1% for the first $5,000 and 3% f
Hoochie [10]

Answer:

Total taxes = $1,520

Step-by-step explanation:

We have two separate calculations for the taxes:

The tax rate for the first $5,000 of Clarisa's gross pay is 1%, so the amount of tax paid in this case is

1% * 5000 = $50

The tax rate for the amount of value over $5,000 (that is, 54,000 - 5,000 = 49,000) is 3%, so the amount of tax is:

3% * 49,000 = $1,470

So, the total amount deducted for state taxes is:

Total taxes = 50 + 1470 = $1,520

In a toy​ store, the ratio of the number of teddy bears to the number of dolls is 3 font size decreased by 5 : font size decreas
pentagon [3]

There are 160 dolls in the store.

<u><em>Explanation</em></u>

The ratio of the number of teddy bears to the number of dolls is given as 3:8

Suppose, the number of teddy bears =3x and the number of dolls =8x

Given that, the store has 60 teddy bears. That means....

3x=60

\frac{3x}{3}=\frac{60}{3} (Dividing both sides by 3)

x=20

So, the number of dolls in the store =8x=8*20=160

What is the circumference of a circle with a radius of 2.5 m?
mixer [17]
The circumference of a circle is always calculated by 2\piR
So if R=2.5 m this circumference is 2*\pi*2.5 m
Which is 5\pi m (choice B)

Hope this helped!
