Under which angle conditions could a triangle exist? Check all that apply.3 acute angles
2 acute angles, 1 right angle
1 acute angle, 1 right angle, 1 obtuse angle
1 acute angle, 2 obtuse angles
2 acute angles, 1 obtuse angle

Answers

Answer:

3 acute angles
2 acute angles, 1 right angle
2 acute angles, 1 obtuse angle

Step-by-step explanation:

We have to check under which condition a triangle will exist.

According to angle sum property of the triangle, the sum of all the three angles of a triangle is 180 degrees.

An acute angle is an angle with a a measure less than 90 degrees

A right angle is an angle with a measure of 90 degrees.

An obtuse angle is an angle with a measure of greater than 90 degrees.

1. It is possible to have triangle with three acute angle

Example: A triangle with all the three angles of 60 degrees

2. It is possible to have a triangle with 2 acute angles and 1 right angle.

Example: A triangle with all the two angles of 45 degrees and one right angle.

3. It is not possible to have a triangle with 1 acute angle, 1 right angle and 1 obtuse angle. It will violate the angle sum property of triangle.

4. It is not possible to have a triangle with 1 acute angle and 2 obtuse angles. It will violate the angle sum property of triangle.

5. It is possible to have a triangle with 2 acute angles and 1 obtuse angle.

Example: A triangle with all the angles of 45 degrees, 40 degrees and 95 degrees

Triangles exist:
3 acute angles2 acute angles, 1 right angle
2 acute angles, 1 obtuse angle

Triangles DON'T exist for:
1 acute angle, 1 right angle, 1 obtuse angle
1 acute angle, 2 obtuse angles

If 120 marks is 60% what is full marks

Answers

percentage is a value by a fraction of 100.
120 marks is equivalent to 60%
this means from the whole amount, 60 % of the whole amount is 120 marks
we need to find the full marks
if 60 % --- 120
then 1 % --- $(120)/(60)$
full marks are 100 %
therefore 100 % - $(120)/(60) * 100$
100 % --- 200 marks
full marks are 200 marks

since 120 is 60 percent we know that 2/3*120+120 will be 100 percent

2/3*120=80
so 80+120=200

So, full marks is 200
