If the shortest leg of a 30 60 90 triangle has length 7 the length of the hypotenuse is?
2*7 = 14 units (the sin of 30° is 0.5 or 1/2 and 7/0.5 = 14) Sin30 = 7/H so H = 7/sin30 = 7/0.5 = 14 (third side is 12.12)
Evaluate sin30 plus cos60-2tan45?
To evaluate sin30 plus cos60-2tan45, we start by finding the exact values of sin30, cos60, and tan45. sin30 = 1/2, cos60 = 1/2, and tan45 = 1. Substitute these values into the expression: 1/2 + 1/2 - 2(1) = 1/2 + 1/2 - 2 = 1 - 2 = -1. Therefore, sin30 plus cos60-2tan45 equals -1.
How do you subtract trig functions?
basic algebra, group like terms Sin30-Sin1=Sin(30-2)=Sin(28)
If the shortest leg of a 30-60-90 triangle has a length of 7 the length of the hypotenuse is?
7/sin30 ie 14 units
