90 (of course) and 55
If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle. A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.) A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)
The other acute angle in that triangle is 40 degrees.
An isosceles right triangle has an angle of 900 and two sides of equal length and two equal angles. Therefore other two angles must be 450.
40 degrees each
Then the other 2 angles will add up to 148 degrees because any triangle has 3 interior angles that add up to 180 degrees

60 degrees. There are 180 degrees in a triangle.
A right angle triangle has a 90 degree angle and its other two angles add up to 90 degrees
The other acute angle in that triangle is 40 degrees.
The angle measure of a triangle is dependent on the type of triangle (scalene, right, isosceles, or equilateral) and also the measures of the other two angles.In a scalene, none of the angles can be predicted without a protractor because none of the angles are equal.In a right triangle only one angle can be undoubtedly determined, the 90° angle (right angle). Knowing this angle's measure, this only limits the possible angle measures of the other two angles. (They must each be less than 90°, but together sum up to 90°)If you know one of the base angles of an isosceles triangle, by the Isosceles Triangle Base Angles Theorem, the other base angle will be congruent. To find the last angle, add the base angles together and then subtract that number from 180.The only triangle that has angle measures that can be determined just by its name is an equilateral, all angle measures equal 60°.
Since the sum of the measures of the angles in a triangle is 180°, and a right angle has a measure of 90°, it follows that the other two angles together have a measure of 90°.
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.
An isosceles triangle, because the angles of a triangle add up to 180 and you already know that one angle measures 120 degrees, the other is 30, and so the unknown angle must also be 30 degrees. Since two of the angles are the same, two of the sides are going to be the same, making it an isosceles triangle.
False because the 3rd angle has to be a right angle of 90 degrees because the 3 angles of any triangle add up to 180 degrees.
The sum of the interior angles of a triangle is 180 degrees. If one angle is 90, that leaves 90 for the other two angles. You can't have another angle of 90 and an angle of 0, so there can only be one angle in a triangle that measures 90 degrees.
A right triangle is a triangle in which one of the three angles measures 90°. In other words, it is a triangle with two sides that are perpendicular to each other.
