Web24 jan. 2024 · Step-by-step explanation: We have been given an image of a right triangle. We are asked to find the measure of angle AMC. Let us find measure of angle A using angle sum property. Since CM is an angle bisector of our given triangle, so it will divide angle ACB into equal parts. We can see that measure of angle ACB is 90 degrees, so … Webb = √ c2 - a2 The law of cosines is a generalization of the Pythagorean theorem that can be used to determine the length of any side of a triangle if the lengths and angles of the other two sides of the triangle are known. If the angle between the other sides is a right angle, the law of cosines reduces to the Pythagorean equation. WebIn a right triangle, the side that is opposite of the 90° angle is the longest side of the triangle, and is called the hypotenuse.

WebIf we consider the right angle, the side opposite is also the hypotenuse. So sin(90)=h/h=1. By pythagorean theorem, we get that sin^2(90)+cos^2(90)=1. So, substituting, 1+cos^2(90)=1 cos^2(90)=0 cos(90)=0 And we see that tan(90)=sin(90)/cos(90)=1/0.

WebThe Law of Sines relates the sides & angles of a triangle, using the sine function. If the triangle’s sides are a, b, & c, across from angles A, B, & C, then the Law of Sines tells us that a/sin (A) = b/sin (B) = c/sin (C). We can use this equation to solve for an unknown side or angle in a triangle.
