Answer to: If the measures of the exterior angles of the acute angles on a right triangle are (6x + 23) and (4x + 17), find the measures of the...
Every triangle has three sides and three angles on the inside. These angles add up to 180° for every triangle, independent of the type of triangle. In a right triangle, one of the angles is exactly 90°. Such an angle is called a right angle. To calculate the other angles, we need ...
right-angled triangle Triangle in which one of the angles is a right angle (90). It is the basic form of triangle for defining trigonometrical ratios (for example,sine, cosine, and tangent ) and for which Pythagoras theorem holds true. Its are a is equal to half the product of the len...

The sum of angles in a quadrilateral (four-sided figure) is always 360 degrees. Based on their measurements, angles are classified as acute, right, obtuse, straight, or reflex. In a right triangle, one angle is exactly 90 degrees, forming an “L” shape. Angles in a straight line add ...

In a right triangle, one of the acute angles measures 45 degrees. What is the measure of the other acute angle? A. 45 degrees B. 60 degrees C. 30 degrees D. 90 degrees 相关知识点: 试题来源: 解析 A。在直角三角形中,两个锐角的和是 90 度。已知一个锐角是 45 度,那么另一个锐角...
The answer is to rely on the other important property of the triangle, the lengths of its sides. They are related to the magnitude of the angles. TL;DR (Too Long; Didn't Read) Find the angles in a right triangle by calculating their sine, cosine or tangent, which are functions of th...
