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.
