Abcd is a convex quadrilateral in which angle bac equals 50 angle cad equals 60 angle cbd equals 30 if e is intersection point of ac and bd find angle aeb?
95 degrees (hint: construct the circumcircle of BCD
If this is opposite is 30 degree angle in a right triangle is 12.5 meters how long is the hypotenuse rounding to the nearest tenth?
If the angle opposite the side of 12.5 meters is 30 degrees then use the sine ratio to find the hypotenuse which works out as 25.0 meters.
A triangle has a 30 degrees angle and a right angle What is the measure of the third angle?
Angle A + Angle B + Angle C = 180 degrees. 30+90+C=180 120+C=180 C=60 degrees.
Fill in the blank If the shortest leg of a 30-60-90 triangle has length 11 the length of the hypotenuse is?
22, The shortest side is opposite the smallest angle. As it is a right angle triangle, the Sine ratio can be used: Sine = opposite/hypotenuse ⇒ hypotenuse = opposite/sine = 11/sine 30o = 11 ÷ 1/2 = 22
How many sides does a regular polygon have if the measure of one interior angle is 150?
if the interior angle is 150 the exterior angle equals 30. since exterior angle equals 360/ by number of sides the number of sides equals 360/30 which equal 12
If an angle decreases from 60 degrees to 30 degrees the trigonometric function that decreases is the sine?
Yes, the sine decreases, and so does the tangent.
What type of angle is this measure A equals 30?
An angle with 30 degrees is an acute angle.
How do I find the length of the hypotenuse with one leg equalling 12 and the opposite angle being 30 degrees?
Rearrange the sine ratio of sine = opposite/hypotenuse: hypotenuse = opposite/sine hypotenuse = 12/sine 30 degrees = 24 Therefore the hypotenuse is 24 units in length.
What is 1 of a 3 of a right angle?
A right angle is 90 degrees and a 1/3 of 90 degrees equals 30 degrees
What is the value of 30 degrees?
sine of 30 degrees
What is the arc function for trigonometric relationships?
The trigonometric function of an angle gives a certain value The arc trigonometric function of value is simply the angle For example, if sin (30 degrees) = 0.500 then arc sine ( 0.500) = 30 degrees
The compliment of a 30 degree angle has a measure of?
The compliment of an angle is found by taking 90 degrees minus the known angle. Therefore, you take 90 minus 30 which equals 60 degrees.
How do you find an angle using sine cosine tangent?
If you know the angle's sine, cosine, or tangent, enter it into the calculator and press <inverse> sine, cosine, or tangent. On MS Calc, in Scientific Mode, using Degrees, enter 0.5, then check Inv and the press sin. You should get 30 degrees. The other functions work similarly.
What is the value of sin 30 degrees?
Sin30 degrees is 0.50000
Why does Sine Theta equal Sine 180 minus Theta?
When you subtract theta from 180 ( if theta is between 90 degrees and 180 degrees) you will get the reference angle of theta; the results of sine theta and sine of its reference angle will be the same and only the sign will be different depends on which quadrant the angle is located. Ex. 150 degrees' reference angle will be 30 degrees (180-150) sin150=1/2 (2nd quadrant); sin30=1/2 (1st quadrant) 1st quadrant: all trig functions are positive 2nd: sine and csc are positive 3rd: tangent and cot are positive 4th: cosine and secant are positive
Sine wave A has a positive going zero crossing at thirty degrees sine wave B has a positive going zero crossing at forty five degrees determine the phase angle between the two signals?
Two sine waves, one with zero crossing at 30 degrees, the other with zero crossing of 45 degrees, have a relative phase angle of 15 degrees. Simply subtract the two angles from each other.
Given a paralleogram ABCD angle A equals 30 plus 5x and angle D equals 15 plus 10x What is x?
9 degrees
