True or false the angle
Ira Lisetskai [31]

Answer:

Second option: False

Step-by-step explanation:

You need to use the following identity:

sin\alpha=\frac{opposite}{hypotenuse}

Let be "x" the lenght of the buildings's shadow.

opposite=x (Lenght of building's shadow)

You can observe in the figure that:

\alpha=75\°\\\\hypotenuse=50ft

Substitute these values into  sin\alpha=\frac{opposite}{hypotenuse} and solve for ""x":

sin(75\°)=\frac{x}{50}\\\\(50)(sin(75\°))=x\\\\x=48.29\°

Therefore, the length of its shadow IS NOT 12.94 feet.

Select the correct answer.

Answer:  Step 5

===================================================

Reason:

The order of operations is PEMDAS

  • P = parenthesis
  • E = exponents
  • M = multiplication
  • D = division
  • A = addition
  • S = subtraction

The multiplication and division are on the same level of precedent, and the same goes for addition and subtraction. Some math textbooks may refer to PEMDAS as BODMAS, which is basically the same thing.

Notice how division comes before addition. So we must compute the 10 \div 2 portion first before adding in step 4.

This is what steps 4 and onward should look like

2 + 10 \div 2\\\\2 + 5\\\\7

So that's why the error is in <u>step 5</u>

If there was parenthesis around the "2+10", and we had (2+10) \div 2, then step 5 given by your teacher would be correct.
