No. An acute triangle only has angles less than 90 degrees. A triangle with a 130 degree angle is obtuse.
A triangle with angles 103 degree, 20 degree, and 57 degree is called
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.
The 3rd angle is 70 degrees which would form a right angle triangle.
It is a right angle triangle and its 3rd angle is 70 degrees.
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 degrees A right triangle has one angle that HAS to be 90 degrees. If the other is 20 degrees, and all three angles need to add to 180 degrees: 90+20+x=180 x=70
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
The third angle measures 85⁰ (20 + 75 + 85 = 180) consequently, the triangle is an acute angled scalene triangle
The measure of the smaller acute angle of the triangle is: 17.46 degrees.
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.

20, 70 and 90 degrees.
70
Scalene
If you mean angles of 150 degrees, 20 degrees and 20 degrees then it is impossible to construct such a triangle because the angles in any triangle add up to 180 degrees and the angles given add up to 190 degrees.
Yes 20 degrees would be an acute angle. This is because it measures less than 90, which is a right angle. Anything below 90 is acute while anything above is obtuse.
