Answer:

7/12

Step-by-step explanation:

30+40+50=120

120 buttons in total

Slove:33/29=46/x. Try to find the answer.
Tju [1.3M]

Answer:

x=40\frac{14}{33}

Step-by-step explanation:

we have

\frac{33}{29}=\frac{46}{x}

Solve for x

Multiply in cross

(33)(x)=(46)(29)

Divide by 33 both sides (Division Property of Equality)

x=46(29)/33

x=\frac{1,334}{33}

Convert to mixed number

x=\frac{1,334}{33}=\frac{1,320}{33}+\frac{14}{33}=40\frac{14}{33}

Triangle JKL is transformed to create triangle J'K'L'. The angles in both triangles are shown.
Margaret [11]

Answer:

The correct option is 3.

Step-by-step explanation:

Triangle JKL is transformed to create triangle J'K'L'. The angles in both triangles are shown.

J = 90°, J' = 90°

K = 65°, K' = 65°

L = 25°, L' = 25°

In a rigid transformation the  image and pre-image are congruent. Reflection, translation and rotation are rigid transformation.

In a non rigid transformation the image and pre-image are similar. Dilation is a non rigid transformation.

In a rigid or a nonrigid transformation, the corresponding angles are same. If the corresponding sides are same, then it is a rigid transformation and if the corresponding sides are proportional, then it is a non rigid transformation.

It can be a rigid or a nonrigid transformation depending on whether the corresponding side lengths have the same measures.

Therefore option 3 is correct.

A radio tower is located 300 feet from a building. From a window in the building, a person determines that the angle of elevatio
DerKrebs [107]

Answer:

The tower is approximately 381 feet high.

Step-by-step explanation:

Refer to the sketch attached. The height of the tower can be found in two parts:

  • The part above the window, and
  • The part under the window.

Each part can be seen as a leg of a right triangle. The other leg is the distance between the building and the tower and is 300-feet long. The angle opposite to the leg is given.

  • The length of the upper part is 300\cdot \sin{42^{\circ}} feet.
  • The length of the lower part is 300\cdot \sin{37^{\circ}}.

The height of the tower is the sum of the two parts:

300\cdot \sin{42^{\circ}} + 300\cdot \sin{37^{\circ}} = 300(\sin{42^{\circ}}+\sin{37^{\circ}}) = 381 feet.
