Subtraction. In order of operations, parenthesis comes first. Since the subtraction term is in the parenthesis, you would do that first. Then it's exponents, multiply, divide, add, and subtract. In the case that there are more than one multiplication/division operation, you would do it in the order from left to right. Same for subtraction/addition. Hope this adds a bit to your knowledge! Have a nice day :)

Julia is standing 2 feet away from a lamppost. If she casts a shadow of 5 feet and the light makes a 20° angle relative to the g

givi [52]

Answer:

2.5477 feet

Step-by-step explanation:

Refer the image attached to understand my solution.

BC = height of lamppost.

DE = Julia

AD = shadow of Julia

BD = 2 feet. AD = 5 feet

BA = BD + AD

= 2 + 5 = 7 feet

In ΔABC

tan 20° = $\frac{BC}{BA} = \frac{BC}{7}$

BC = 7 * tan 20°

BC = 2.5477 feet

SO the height of lamppost = 2.5477 feet

What is the reason for statement 4 in this proof?

Naddika [18.5K]

It's the reflexive property because it's just relating it to itself (def. of reflexive)

As we all know: A=A, B=B, mx=mx, nothing changes.

So the answer is D
