Question

Can somebody please help to answer the above question and explain please

Answer 1

The correct answer is 11.3

Answer 2

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.
