Answer:

B) 55°

Step-by-step explanation:

The ∑ of all interior angles of a triangle is 180°.

When you see a square in a angle (as seen in the bottom left of the triangle), it means that it is a right angle, or 90° in measurement.

Set the equation:

180 = x + 90 + 35

First, combine like terms:

180 = x + (90 + 35)

180 = x + 125

Next, subtract 125 from both sides of the equation to isolate the x:

180 (-125) = x + 125 (-125)

x = 180 - 125

x = 55

55°, or B) is your answer.

On a clear day you can see about 25.2 miles from the upper observation platform of the Eiffel tower in Paris. Using the formula

fredd [130]

Answer:

D. 914 feet

Step-by-step explanation:

We are given the distance that a person can see on a clear day from the upper observation platform of the Eiffel tower in Paris. We are then required to estimate the height of the upper observation platform using the formula;

$d=\frac{5}{6}\sqrt{h}$

Where d is the distance and h the height of the upper observation platform. The first step would be to solve for h, that is make h the subject of the formula in the above equation;

We multiply both sides of the equation by the reciprocal of 5/6 which is 6/5;

$\sqrt{h}=\frac{6}{5}d$

The next step is to eliminate the square root on the Left Hand Side of the equation by squaring both sides;

$h=1.44d^{2}$

Given d is 25.2, h becomes;

$h=1.44*25.2^{2}\\h=914.4576$

To the nearest whole number, h becomes 914

1/2x3+1/4x2 =<br> i need to know please

FrozenT [24]

In complex calculations like this, the precedence goes like this

B = Brackets
O = Of (or Exponent)
D = Division
M = Multiplication
A = Addition
S = Substraction

So, in your formula, it will go like this

1/2x3+1/4x2
= 0.5 x 3 + 0.25 x 2
= 1.5 + 0.5
= 2

Hope this helps.
