True or False triangle ABC with right angle at C if C equals 24mm and A equals 16.67 then angle B equals 26?
False : Cos B = 16.67/24 = 0.6946 : Therefore angle B = 46° (not 26°).
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals?
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals: 40 degrees.
How do you find hypotenuse c angle a equals 30 deg side b equals 5 mm?
To find the hypotenuse with angle a and side b, we use the identity below:cos(a) = b/cWe have a and b, and to find c, we multiply both sides by c and divide both sides by cos(a):c = b/cos(a)c = 5/cos(30)c = 32.41460617mm
What is cos in a math problem?
Its a ratio in a right angle triangle, cos angle = adjacent / hypotonuse.
Determine the measure of angle A if 0 degrees is smaller than or equal to A which is smaller than or equal to 90 degrees and cos125 degrees equals negative cos A?
cos(125) = cos(180 - 55) = cos(180)*cos(55) + sin(180)*sin(55) = -cos(55) since cos(180) = -1, and sin(180) = 0 So A = 55 degrees.
What is the cos of a 40 degree angle?
0.766
If θ is an acute angle and sin θ equals 2 then cos θ?
it equals 4
What is the angle for cos equals 0.2874?
Well, isn't that just a happy little question! To find the angle for cos equals 0.2874, you can use the arccos function on a calculator. This function will give you the angle in radians where cos of that angle is equal to 0.2874. Just remember to breathe, take your time, and enjoy the process of discovering the beauty of mathematics.
What is cos of a negative angle?
The cosine function is an even function which means that cos(-x) = cos(x). So, if cos of an angle is positive, then the cos of the negative of that angle is positive and if cos of an angle is negative, then the cos of the negative of that angle is negaitive.
Prove that sin 90 equals cos 50sin 40- cos 40 sin 50?
Sorry, but cos(50)sin(40) - cos(40)sin(50) is -0.1736, which is not even close to sin(90) which is 1.This does not work in radians, either. Please restate your question.
True or False triangle ABC with right angle at C if C equals 24mm and A equals 16.67 then angle B equals 26?
False : Cos B = 16.67/24 = 0.6946 : Therefore angle B = 46° (not 26°).
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals?
In a right triangle with the hypotenuse c equals 10 and the angle A equals 50 degrees the angle B equals: 40 degrees.
Abc is a right triangle and angle a equals 40 what is the angle ecd?
The angle is 50 degrees.
Abcd is a quadrilateral angle a equals 40 degrees and angle b equals 150 degrees could abcd be a trapezoid?
never
Abcd is a quadrilateral in which angle a equals 40 degrees and angle b equals 150 degrees could abcd be a parallelogram?
never
In the triangle the angle at a is 40 degrees less than the angle at b and 20 degrees less than the angle at c what is the size of each angle?
if the angle at a equals X then the angle at b equals X+40 and the angle at c equals X+20 the sum of the angels in a triangle is 360 degrees so: X + X+40 + X+20 = 360 3X + 60 = 360 3X = 300 X = 100.
How do you find hypotenuse c angle a equals 30 deg side b equals 5 mm?
To find the hypotenuse with angle a and side b, we use the identity below:cos(a) = b/cWe have a and b, and to find c, we multiply both sides by c and divide both sides by cos(a):c = b/cos(a)c = 5/cos(30)c = 32.41460617mm
