angle C= 90 degrees, angle A =44 degrees, angle B = 46 degrees
c Hyp = 136in explain how do you figure the other two sides... class has no texts, and lectures only, haven't a clue on these.. thanks

The definition says that : sin(angle) = opposite / hypotenuse.
Therefore, sin(A) = a / 136, so, a = 136 * sin(44º) = 94.5 inches.
And, sin(B) = b / 136, so, b = 136 * sin(46º) = 97.8 inches.

1st draw a circle with diameter 136
then mark a diameter which serves as hypotenuse of the triangle
now draw a line making an angle 46 degrees with tht line from an end of the line.
it cuts the circle at a point which is a vertex of the triangle.
now join this vertex with the other end of the hypotenuse
v get the required triangle
got the point?
main funda is we are using the principle tht angle in a semicircle is 90 degrees.

From Chief SOHCAHTOA
sin 44=a/136 a=94.5 in
sin 46=b/136 b=97.8 in
