What type of angle is missing in a triangle where the other two angles are 45� and 75�?

The missing angle in the triangle with angles 45� and 75� is a right angle, which measures 90�. In a triangle, the sum of all three interior angles always adds up to 180�, so the missing angle would be 180� - (45� + 75�) = 60�.

In a triangle with angles of 60� and 50�, what is the measure of the missing angle?

The measure of the missing angle in the triangle can be found by subtracting the sum of the known angles (60� + 50� = 110�) from the total of 180� (since the sum of angles in a triangle is always 180�). Therefore, the missing angle would be 70� (180� - 110� = 70�).

In a right triangle with a 30� angle, what is the measure of the missing angle?

In a right triangle with a 30� angle, the missing angle would be 60� since the sum of angles in a triangle is always 180 degrees. Therefore, in a right triangle with a 30� angle, the missing angle would be 60�.

If one angle in a triangle is 120� and another angle is 40�, what is the measure of the missing angle?

The missing angle in the triangle with one angle of 120� and another angle of 40� can be found by subtracting the sum of the two known angles from 180�, as the sum of all angles in a triangle is always 180�. Therefore, the missing angle would be 20� (180� - 120� - 40�).

In a triangle with angles measuring 70� and 90�, what is the measure of the missing angle?

The sum of the angles in a triangle is always 180�, so the missing angle in this triangle can be found by subtracting the sum of the other two angles from 180�. Therefore, the missing angle would be 20�.

If two angles in a triangle are congruent and measure 60� each, what is the measure of the missing angle?

The measure of the missing angle in the triangle would be 60� as well, as the sum of the angles in a triangle always adds up to 180�. Since two angles are already 60� each, the third angle, or the missing angle, must also be 60� to satisfy the condition.

In an isosceles triangle with two angles measuring 50� each, what is the measure of the missing angle?

In an isosceles triangle with two angles measuring 50� each, the sum of all angles in a triangle is always 180�, so the missing angle would be calculated as 180� - 50� - 50� = 80�. Therefore, the measure of the missing angle in the isosceles triangle is 80�.

If the three angles in a triangle are 40�, 80�, and x�, what is the value of x?

The sum of the interior angles in a triangle is always 180�. So, by adding the given angles 40� and 80�, we get 120�. Therefore, x� must be 60� in order for the sum of the three angles to be 180�.

In a triangle with angles measuring 55� and 90�, what is the measure of the missing angle?

The sum of the angles in any triangle is always 180�. Therefore, if we have angles measuring 55� and 90� in a triangle, the missing angle can be calculated by subtracting the sum of the given angles from 180�. Thus, the missing angle in this triangle would be 180� - 55� - 90� = 35�.

If two angles in a triangle measure 25� and 115�, what is the measure of the missing angle?

The measure of the missing angle in the triangle can be found by subtracting the sum of the two given angles from 180� since the sum of all angles in a triangle is always 180�. Therefore, the missing angle would be 180� - (25� + 115�) = 40�.
