It is a right angle triangle and its 3rd angle is 70 degrees.

Any triangle that has an angle measuring 90 degrees is a right triangle.

The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle

right triangle and the other angle would be 70 degrees. Hope I helped :)

The 3rd angle is 70 degrees which would form a right angle triangle.

A triangle has 180 degrees.A right triangle has exactly one angle measuring 90 degrees.If you know that one of the other angles of the triangle is 20 then your third angle is:180-90-20 = 70 degrees.

70 degreesA right triangle has a right angle that measures 90 degrees, and the total number of degrees in a triangle is 180 degrees.180 - 90 leaves 90 for the other two, and 90 - 20 = 70

That depends on the sizes of the other 2 angles if it's a right angle triangle then the other acute angle would be 70 degrees.

Each exterior angle measures 20 degrees Each interior angle measures 160 degrees

The vertex angle of an isosceles triangle is the angle opposite the base of the triangle. Therefore, the other two remaining angles of the triangle are congruent. so, in this problem: Let x = m of angle B Let x1 = m of angle C Let 3x + 20 = m of angle A x + x + 3x + 20 = 180 5x + 20 = 180 5x = 160 x = 32 degrees Since angle B and C are congruent, the measure of angle C = 32 degrees.

Not possible - the smallest interior angle for a regular polygon is 60 degrees - which creates an equilateral triangle.

20 degrees

No. For example, say the two angles are 10° and 20°. Then the other angle is 180°-10°-20°=150° and that is not a right angle. But if the triangle has two equal acute angles of 45 degrees then the 3rd angle must be 90 degrees which will form a right angle triangle.
