Divide the triangle in half to get 2 right-angle triangles. Then, cos (base angle).
cos = 1/2 (b/h * 10)
cos = 1/2 (8/10 * 10)
cos = 4/10,
cos = 66.42 degrees, which simplifies to 66 degrees.
Are you talking about the angle A. If you are then at what point of the triangle is the angle A.
If you mean angles then it is a right angle triangle or an isosceles right angle triangle

180 - twice 42
57.5 degrees
The two equal sides each measure 8 inches
80 degrees

The sum of all three interior angles of any triangle, isosceles or not, is 180 degrees.
It is a right angle triangle.
57.5 degrees
180 - twice 42
A triangle that has one right angle and is isosceles is called an isosceles right triangle.
90 degrees. This is an isosceles right triangle, standing on its hypotenuse.
130 degrees is the measure of the base angles of an isosceles triangle whose vertex has a measure of 50 degrees.
