find c in the upside down triangle

Answer 1

71°

Explanation:

What is an angle?

An angle is a measure of a turn, measured in degrees or °. Angles are made up of two rays, forming the sides of the angle.

If we know that all 3 of a triangle's angles must add up to 180°, we can use this expression to solve for the missing angle:

angle 1 + angle 2 + angle 3 = 180°

Inserting our 2 angles into the expression gives:

68° + 41° + angle 3 = 180°

To solve for angle 3, we can rearrange the equation above:

180 - (68 + 41) = angle 3

Solving this equation gives us:

71° = angle 3

Therefore, the measure of the missing angle is 71°

Answer 2

71°

Explanation:

What is an angle?

An angle is a measure of a turn, measured in degrees or °. Angles are made up of two rays, forming the sides of the angle.

If we know that all 3 of a triangle's angles must add up to 180°, we can use this expression to solve for the missing angle:

• angle 1 + angle 2 + angle 3 = 180°

Inserting our 2 angles into the expression gives:

• 68° + 41° + angle 3 = 180°

To solve for angle 3, we can rearrange the equation above:

• 180 - (68 + 41) = angle 3

Solving this equation gives us:

• 71° = angle 3

Therefore, the measure of the missing angle is 71°
