What rise does a 30 degree angle give over 5 m?
5*sin(30) = 2.5 metres.
The lentgh of the hypotenuse of a 30 -60 degree right triangle is 7.5 meters find the length of the opposite side of the 30 degree angle?
It is: 7.5*sin(30) = 3.75 meters
The shorter leg of a 30-60-90 degree triangle is 6 what is the length of the other leg?
Use the Sine rule. If L is the length of the longer leg, then L/sin(60) = 6/sin(30) So that L = 6*sin(60)/sin(30) = 12*sin(60) = 12*sqrt(3)/2 = 10.39 units.
What is the value of x in a 90 degree triangle with a hypotenuse of 30 and a 45 degree angle x is the opposite of the 45 degree angle us a trigonometric function?
Use and rearrange the sine ratio: 30*sin(45) = 21.21320344 units
Sin A equals 0.3779 find the degree and how?
22.20366435 sin^-1(0.3779)
