The correct answer is 11.3
Aloiza [94]3 years ago

Answer:

h= 11.3cm  

or h= 11.30cm  

or 11cm to 2sf.

Step-by-step explanation:

Tan (37) = 0.7535540501  

15 x 0.7535540501   = 11.30331075  

h = 11.30331075  

So option 1 is Tan (angle) = A   then A x length

A = Angle 37 and  multiply the product by its length 15

-----

A way to know you got the correct side is check hypotenuse

but convert angle to 90-37 = 53

Sin (53) = 0.79863551  then divided by

15/ 0.79863551 = 18.7820348735

Slant hypotenuse = 18.7820348735

Divided by base 15 (base) but we can convert angle to 53

------

If ever your confused with angle stick to sin and check the second way of doing Sin by entering your first h measure exactly same way to replace 15

When you type in sin (37) it only works on this way Side (measure only)

There is tan and just this Sin to find h

Sin (37) = 0.6018150232  then divided by

11.30331075 /0.6018150232  

slant hypotenuse = 18.7820348683

but if you did it both angles the wrong way one would round show 14.15327843 when x it by h we know this is wrong as the side measure once found using tan =side measure = find h  would be imputed as the main number to divide the product of Sin (37) same measure to counter-check so 1+3 makes sense for finding sides low angles just the same when you turn triangle to its side its base and top angles that work tan and sin using same numbers side findings from tan use for sin and only same angles 1+3.

What is the quotient? Negative StartFraction 3 over 8 EndFraction divided by negative one-fourth
anyanavicka [17]

Answer:

\dfrac{3}{2}

Step-by-step explanation:

We are given 2 fractions.

1st fraction is Negative StartFraction 3 over 8

i.e.

-\dfrac{3}{8}

2nd fraction is negative one-fourth

i.e.

-\dfrac{1}{4}

We have to find the quotient when 1st fraction is divided by 2nd fraction.

<u>Definition</u> of quotient is given as:

Quotient is the result obtained when one number is divided by other number.

-\dfrac{3}{8} \div -\dfrac{1}{4} \text{ is to be calculated.}

\div is converted to \times and the 2nd fraction is reversed i.e.

if the fraction is \frac{p}{q} it becomes \frac{q}{p} and the sign \div is changed to \times.

Solving above:

-\dfrac{3}{8} \times -\dfrac{4}{1}\\ \text {Multiplication/Division of 2 negative number gives a positive number}\\\Rightarrow \dfrac{3}{2}

So, the quotient is \frac{3}{2}.

Look at the right triangle ABC:
prisoha [69]

Answer:

The first incorrect justification is in step 2.

Step-by-step explanation:

<u>Step 2</u>. BC2 = AC • DC  

2. BC ÷ DC = BC ÷ AC because triangle ABC is similar to triangle BDC

It's supposed to be AC ÷ BC not BC ÷ AC.
