In a right-angled triangle, the degree measures of the largest and smallest outside
February 1, 2021 | education
| In a right-angled triangle, the degree measures of the largest and smallest outside catches are 8: 5. Find the acute angles of this triangle.
The minimum outside angle at the vertices of a right-angled triangle is the outside angle at the vertex of the right angle.
The outer angle ACE, at the apex of the right angle, is 900.
Then 5 * X = 90.
X = 16.
Then the largest angle ВAD = 8 * 16 = 144.
The inner corner of the BAC, adjacent to the outer corner of the BAC, the sum of which is 1800.
Then the angle BAC = (180 – ВAD) = (180 – 144) = 36.
The sum of the acute angles of a right-angled triangle is 90, then the angle CAB = (90 – BAC) = (90 – 36) = 54.
Answer: The acute angles of the triangle are 36 and 54.
