How do I find Sin A .42 is A is an acute angle. And how do i enter that on a calculator?

If sin(A) = 0.42 then A = arcsin(0.42).
On calculators, the arcsin key is usually reached by using another key before the sin key, and is shown as "sin to the power -1".
Make sure that your calculator is set to degrees rather than radians (to check this, try sin(90). If the answer is 1 the calculator is in degree mode; if it is 0.8940 it is in radian mode.

How do you find an 87.5 acute angle?
87.5 < 90 and so it is an acute angle.
What is the supplement of an acute angle?
To find the supplement of an acute angle, do the following. Supplements must add to 180 degrees, therefore: x=the measure of the acute angle 180-x is the equasion to find the supplement Good Question!
How do I find the tangent of an angle?
Use a calculator. There is no simple way to calculate it.
In the right triangle the ratio of the measures of the two acute angles is 4 1 what is the measure in degrees of the larger acute angle?
The 4 to 1 ratio of the two acute angles can be restated as the larger acute angle is four times as large as the smaller acute angle. Since the sum of all angles in a triangle equal 180 degrees, the sum of the two acute angles will be equal to 90 degrees. The remaining 90 degrees are found in the right angle present in all right triangles. If we divide the 90 degrees of the acute angles by 5 (to get the five parts of our ratio) and ascribe 4 of those parts to the largest acute angle we can find the size of that angle by multiplying (90 / 5) x 4 = (18) x 4 = 72. Therefore the largest acute angle is 72 degrees and the smaller acute angle is 18 degrees for a total of 90 degrees. Answer: 72 degrees
How do you find the hypotenuse with only a leg and a degree?
If it's a right angle triangle and an acute angle plus the length of a leg is given then use trigonometry to find the hypotenuse.
How do you find an acute angle?
To find an acute angle you need to find out if it is less than 90 degrees.
How do you find an 87.5 acute angle?
87.5 < 90 and so it is an acute angle.
Where would you find a acute angle?
3 names of where you would find an acute angle is: Triangle, cone and a star.
Where would you find the shape of an acute angle?
An acute triangle
What is the example of acute angle?
An acute angle is an angle of less than 90°. A 90° angle is a right angle, the angle you find at two adjoining edges of a square. An angle smaller than a right angle is called an acute angle, while an angle larger than it is called and obtuse angle.
How do you convert sine to degrees?
Sine can be found in degrees by taking the length of the opposite side and hypoteneuse. Then divide the opposite side by the hypoteneuse. Any calculator can be used to find this. for example, if the hypoteneuse side was 7, and the opposite side was 3, and you labeled the angle "A", then it would be "sineA= 3/7" ...... then A=sin^-1 (3/7) and you put that in your calculator and the answer you get is the angle in degrees (if the calculator is in degrees mode, and if the angle is an acute angle).
Cosecant on calculator?
Cosecant is the reciprocal of sine. To find the cosecant of an angle using a calculator, find the sine of that angle (using the Sin button) and then divide 1 by the result.
What is the area of an acute triangle?
the area referrers to the length and circumference of the triangle it self. The measurement matters to find the acute angle it self as a angle not a triangle
How do you find out if triangle is obtuse acute or right?
If it has an angle over 90 degrees, it's obtuse. If it has an angle exactly 90 degrees, it's right. Otherwise, it has three acute angles, and is acute.
How do you know the angle without using a calculator?
To find an angle without using a calculator, you will need to use a trig identity. Determine which angle it is and use its corresponding trig identity.
What is the supplement of an acute angle?
To find the supplement of an acute angle, do the following. Supplements must add to 180 degrees, therefore: x=the measure of the acute angle 180-x is the equasion to find the supplement Good Question!
How do you find the length of a leg and a hypotenuse when you only have one measure of one leg?
It's impossible. Trigonometrical functions can be used, but only if the measure of one of the acute angles is given. If it is given, then knowing that the right angle is 90 degrees you can solve for the other acute angle. Then use sine, cosine, or tangent to relate the measure of the sides, for which a calculator is necessary.
