What is the value of sin30?
The answer is 1/2.
What is the Circumference of an 18 inch hexagon?
54 inches Because: sin30=x/9 sin30 is the degrees that makes the apothems angle of depression and 9 is the radius.
What are the equal lengths of an isosceles triangle which has 2 equal base angles of 75 degrees and an area of 100 square cm showing key stages of work?
Formula: 0.5*a*b*sinC = area or 0.5*side2*sinC = area Apex angle: 180-75-75 = 30 degrees So: 0.5*side2*sin30 = 100 square cm Side as subject of the formula: side = square root of (200/sin30) = 20 Therefore: each equal sides of the isosceles triangle are 20 cm in length
Class xth important question section?
cos60 + sin30 = tan90
What is the sin of a 30 degree angle?
sin30 is 1/2 or 0.5
Relationship between tignomentary ratios 30 and 60 degree?
sin30=1/2c0s60=1/2
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)
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
What is the value of sin 30 degrees?
Sine(30) = 0.5 or 1/2
What is the exact value of sin150?
sin150 is 0.5 Remember that 150o is 5π/6 radians and the reference angle is π/6 or 30o. sin30 is 0.5
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.
