Suppose that the measures of two angles of a triangle are 15 ∘ and 135 ∘ and that the side that is common to these two angles is 71 inches long. Following is a reasonably accurate diagram for this triangle. Determine the lengths of the other two sides of the triangle and the measure of the third angle. WebAnswer (1 of 2): No. An acute angled triangle cannot have acute exterior angles. The sum of the angles on a straight line should be equal to 180°. So if one angle is acute the other must be obtuse. extended stay tampa spruce

WebA special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle. A "side-based" right triangle is one ... WebFirst, remember that the three angles in any triangle add up to 180 degrees. If the angles are x, y, and z, then: x + y + z = 180. Next, remember that the largest angle is 90 degrees (let’s say that angle is z). Then: x + y + 90 = 180. x + y = 90. Then, recall that the two smaller angles have the same measure.
