Correct question is;

Type the correct answer in the box bellow: If cos x = sin(20 + x)° and 0° < x < 90°, the value of x is ...........

Answer:

x = 35°

Step-by-step explanation:

We are told that;

cos x = sin(20 + x)°

and 0° < x < 90°

From trigonometric identities, we know that;

cos x = sin (90 - x)

Applying to our question gives;

sin (90 - x) = sin (20 + x)°

Comparing both sides, we have;

90 - x = 20 + x

Rearranging;

90 - 20 = x + x

70 = 2x

x = 70/2

x = 35°

A varies inversely as the square of B. If A is 1 when B is 3, find A when B is 5
RideAnS [48]

Answer:

0.36

Step-by-step explanation:

A= K/B^2

K= A × B^2

K= 1 × 3^2

K= 1×9

K= 9

Therefore if B is 5 then A can be calculated as follows.

K= A × B^2

9= A × 5^2

9= A × 25

9= 25A

A= 9/25

A= 0.36

Hence A is 0.36

A rectangular solid object is 3 in. high, 6 in. long and 2 in. wide. What is its volume?
inn [45]

Answer:

The volume is 36 inches cubed.

Step-by-step explanation:

The volume of a rectangular prism is W*L*H.

You are given the H=3i, W=2 in, and L=6 in.

So now we plug into our formula for the volume of a rectangular prism which will result in 2*6*3=12*3=36.

The volume is 36 inches cubed.

I am so lost in geometry. Help?
icang [17]

27. To find this one, you would need to use the Pythagorean theorem, making the answers B and D.

28. Make a mark with your pencil. Set the compass so it has a point on each end of line ab. Now set the side of the compass without the pencil on the mark you already made and mark it. Use the straight edge to make the marks into a line. Now set the compass to the size of line cd. Set the non pencil side on one of the point of your line you just made. Make a mark. Now erase the part of the line that is the length of cd so it is ab-cd.

29. (4,3) I look at the distance between the x coordinates and add it to the end that is the middle and do the same for the y.

30. Put either side of the compass on the ends of the line. put the non pencil side on point x. Make a decent sized arc with the compass. Pick however many spots you needed and mark them. Use the straight edge to connect these points to point x. Repeat for all the points. Erase the arc.

Hope this helped. Let me know if you need any more help!
