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?
Sin30 degrees is 0.50000
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.
