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 ...

When you choose which of the two angles (ø) in a right triangle you want to find, you establish three sides in relation to it. The line that touches the angle and extends to the 90-degree angle is called the adjacent side, while the side opposite the angle is the opposi...
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 ...
A. 30 degrees B. 60 degrees C. 90 degrees D. 150 degrees 相关知识点: 试题来源: 解析 B。在直角三角形中,两个锐角的和为 90 度。已知一个锐角为 30 度,所以另一个锐角为 90 - 30 = 60 度。选项 A 是已知的锐角角度,选项 C 是直角的角度,选项 D 不符合三角形内角和为 180 度。反馈...
First, we show how to construct geodesic triangles with either one, two, or three interior right angles, whenever it is possible. Second, we report a construction of triples of points for which the dual Pythagorean theorems hold simultaneously at a point, yielding two dual pairs of dual-type...

Now we know the measure of two angles are 39∘ and 69∘. By the Triangle Sum Theorem, the sum of all angles in a triangle is 180∘, so the final angle is 72∘ . Therefore, the largest angle in the triangle is (B) 72.反馈...
