Answer:

11.820 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that ...

Sin = Opposite/Hypotenuse

The length of the ladder is the hypotenuse of a right triangle with 52° as the base angle. The side opposite is the height up the building where the top of the ladder rests. So, you have the relation ...

sin(52°) = height/(15 ft)

Multiplying by the denominator gives you ...

height = (15 ft)·sin(52°) ≈ 11.820 ft

___

You may need to round this number appropriately.

Answer:

9 and 4 or D

Step-by-step explanation:

If you're not quite sure how to solve, let's find the answer by process of elimination.

If the area of a rectangle is 36 square inches, we can try option one.

7 * 6 = 42, not 36, so option A is incorrect.

Option two:

12 * 3 = 36 so option B is correct.

Option 3:

10 * 3 = 30 so option C is incorrect

Option 4:

9 * 4 = 36 so option D is correct

Now for perimeter:

9 + 4 + 9 + 4 = 18 + 8 = 26.

12 + 12 + 3 + 3 = 24 + 6 = 30

Thus, an answer of 9 and 4 is correct.

Need answer asap evaluate the limit or state that the limit does not exist 7n-8n/2n
bagirrra123 [75]
\lim_{n \to \ 0 }  \frac{7n-8n}{2n} =  \lim_{n \to \ 0 }  \frac{-n}{2n} 
=  \lim_{n \to \ 0 }  \frac{-1}{2} =  \frac{-1}{2}

Could somebody please help me find the answers for 'x' for these pictures?
djyliett [7]

Answer:

(in order) #1

for the first one you have a vertical angle. Vertical angle is basically any 2 lines who intersect each other. The opposite sides will be congruent.

So in this case

2x+8 and 110 are oppostie sides.

2x+8=110

Which is x= 51

#2

For the second one you have supplementray angles

Now for supplementary angles its basically 2 angles added up that form a straight line And 180 degress is always the measure of a straight line. SO in this case we do

9x+12x+75=180

Which is x=5

#3

This is also a vertical angle pair and their congruent just like #1

So 5x+5=65

x=12
