If 7/12 has the same value as a fraction x/60.say what number is x?​
Bad White [126]
Answer: x = 35

Explanation:

To obtain a fraction of the same value, you must multiply or divide by the same number both on the denominator and numerator.
If 60/12 = 5, then that means the fraction 7/12 mustve been multiplied by 5. And since the number must be multiplied or divided by the same number,

7 x 5/12 x 5 = 35/60

Hope this helps, brainliest would be appreciated :)

Answer:

  91.8 ft

Step-by-step explanation:

So we can talk about the diagram, let's name a couple of points. The base of the tree is point T, and the top of the tree is point H. We want to find the length of TH given the length AB and the angles HAT and ABT.

The tangent function is useful here. By its definition, we know that ...

  TA/BA = tan(∠ABT)

and

  TH/TA = tan(∠HAT)

Then we can solve for TH by substituting for TA. From the first equation, ...

  TA = BA·tan(∠ABT)

From the second equation, ...

  TH = TA·tan(∠HAT) = (BA·tan(∠ABT))·tan(∠HAT)

Filling in the values, we get ...

  TH = (24.8 ft)tan(87.3°)tan(9.9°) ≈ 91.8 ft

The height <em>h</em> of the tree is about 91.8 ft.
