What is the measure of angle ABC?

180°
Angle ABC is a straight angle, or 180°.

Which angle is equal of angle B?

We can prove angle A equal to angle B by proving opposite sides of angle A and B also equal. Also cos of any angle equal to the ratio of adjacent to hypotenuse.

What is the measure of ABC Why?

The size of an angle is measured in degrees (see Angle Measures). When we say ‘the angle ABC’ we mean the actual angle object. If we want to talk about the size, or measure, of the angle in degrees, we should say ‘the measure of the angle ABC’ – often written m∠ABC.

What is the side included between the angles A and C of triangle ABC?

The side included between ∠A and ∠B of ∠ABC is is AB. No matter how you name the triangle, the side between ∠A and ∠B will always be AB. See the attachment. So your answer is (C) AB.

Is A and B are complementary angles then?

The correct option is (d) = sec A = cosec B Two angles are said to be complementary if their sum is equal to 90° .

How do you find AB and C of a triangle?

Hypotenuse calculator The hypotenuse is opposite the right angle and can be solved by using the Pythagorean theorem. In a right triangle with cathetus a and b and with hypotenuse c , Pythagoras’ theorem states that: a² + b² = c² . To solve for c , take the square root of both sides to get c = √(b²+a²) .

What is the value of angle M if angle ABC is 40°?

90° − 40° = 50° Angle m is 50°. Angle ABC is 90° , and angle m is only part of this right angle. It is less than 90°.

What is the measure of angle C?

We have been given an image of a triangle and we re asked to find the measure of angle C. Therefore, the measure of angle C is 70 degrees and option C is the correct choice. Likewise, what is M angle A? , mean you are referring to the angle itself (the actual physical angle).

How do you find the area of an ABC triangle?

In a triangle ABC, angle B=90, angle C=60, angle A=30 and BC=12cm. What is the area of the triangle? AB/sinC = BC/sinA = CA/sinB.

What is angles angle?

Angles Angle- An angle is formed by two rays with a common endpoint. Angles are measured in degrees (°). Straight Angle= 180°Right angle= 90° Acute Angle> 0° and 90°Obtuse Angle> 90° and 180°
