Answer to Problem 33SGR
The measure of the unknown triangle is
The triangle is isosceles triangle
Explanation of Solution
Given:
The sum of measure of all three angles of a triangle is equal to
Observe the triangle. It is a right angled triangle hence one of its angle measures will be equal to
In the question, the measure of given angles is
Thus,
Or,
Or,
Thus, the measure of the unknown triangle is
Clearly two angles and two sides are equal to each other and hence the triangle is isosceles triangle.
Conclusion:
Thus the triangle is isosceles triangle and the measure of the unknown triangle is
