The base is 13 units and the height is 6 units so use these dimensions to determine the 3rd side of the triangle.
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
The third angle is 34.5 degrees
If you're talking about a triangle, the third angle is 80 degrees.
You need the measures of two sides and for the triangle to be a right triangle to figure out the third side.
25 degrees
An isosceles triangle.
The third angle measures 18 degrees.
...a right triangle.
A triangle with the third angle that measures 30 degrees.This triangle is not isosceles nor equilateral but has one obtuse angle.
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
An isosceles triangle has two sides with equal measures. The third side can be any length.
A right angle triangle and the third angle measures 60 degrees
The third angle is 34.5 degrees
63
This would be an isosceles triangle.
You need the measures of two sides and for the triangle to be a right triangle to figure out the third side.
If you're talking about a triangle, the third angle is 80 degrees.
