What is the sum of the angles in a triangle?

The sum of the angles in a triangle is always 180 degrees.

What is the missing angle in a triangle with angles measuring 30� and 60�?

The missing angle in a triangle with angles measuring 30� and 60� would be 90�. In a triangle, the sum of all three interior angles always equals 180�. Thus, by subtracting the sum of the given angles (30� + 60� = 90�) from 180�, we find that the missing angle in this triangle is 90�.

If one angle in a triangle measures 70� and another is 45�, what is the missing angle?

The missing angle in the triangle can be found by subtracting the sum of the two given angles from 180� (the total sum of angles in a triangle). In this case, the missing angle would be 180� - 70� - 45� = 65�.

In an isosceles triangle, if one angle measures 50�, what is the measure of each of the other two angles?

In an isosceles triangle, where two angles are equal, and since one angle measures 50�, the other two angles must also be equal in an isosceles triangle. Therefore, each of the other two angles would also measure 50� in this case.

In a right-angled triangle, if one angle measures 35�, what is the measure of the right angle?

The measure of the right angle in a right-angled triangle is always 90�, regardless of the measure of the other angles. Therefore, in this case, if one angle measures 35�, the right angle would still be 90�.

What is the missing angle in an equilateral triangle?

The missing angle in an equilateral triangle is 60 degrees, as all angles in an equilateral triangle are equal and add up to 180 degrees.

In a scalene triangle, if one angle measures 85� and another measures 55�, what is the measure of the remaining angle?

In a scalene triangle, the sum of all three angles is always 180�. Given that one angle is 85� and another is 55�, the measure of the remaining angle can be calculated by subtracting the sum of the other two angles from 180�. So, 180� - 85� - 55� = 40�. Therefore, the measure of the remaining angle in the scalene triangle is 40�.

If the measure of one angle in a triangle is twice the measure of another angle, and the third angle is 40�, what are the measures of the other two angles?

The one angle that is twice the measure of the other angle is 80�, since the third angle is 40�. Therefore, the other two angles are 80� and 40�.

In a triangle, if one angle measures 75� and another is 60�, what is the missing angle?

The missing angle in the triangle can be found by subtracting the sum of the given angles from 180� (the total sum of the angles in a triangle), so the missing angle would be 45� (180� - 75� - 60� = 45�).

In an obtuse triangle, if one angle measures 120� and another measures 30�, what is the measure of the remaining angle?

The measure of the remaining angle in an obtuse triangle can be found by subtracting the sum of the given angles from 180�. Therefore, the measure of the remaining angle in this triangle would be 30� (given angle) + 120� (given angle) = 150�, and 180� - 150� = 30�. Hence, the measure of the remaining angle in this obtuse triangle is 30�.
