How do you find the angle of ABC?

What does ABC mean angle?

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. However, many times we will see ‘∠ABC=34°’.

What is the value of angle ABC?

⇒∠ABC=180o−65o=115o.

What is the measure of ABC in the figure?

Lines and Angles In the given figure, the measure of ∠ABC is: 80° 20°

What kind of triangle is ABC?

A triangle which has all the three angles acute that is, less than 90°, is called an acute angled triangle or acute triangle. In other words, a triangle is which all the three angles are acute is called an acute-angled triangle. In the given figure ∠A, ∠B and ∠C are acute angle. Thus, ∆ABC is an acute-angled triangle.

What is the value of a b/c If a B is twice the value of C?

The value of a + b + c if a + b is twice the value of c is 3c.

What is the value of Ay in 13 20 AX?

The value of y is -8.265.

What is this angle?

In geometry, an angle can be defined as the figure formed by two rays meeting at a common end point. An angle is represented by the symbol ∠. Here, the angle below is ∠AOB. Angles are measured in degrees, using a protractor.

Which angle is 45 degree?

right angleIn a right angle, the two arms are perpendicular to each other. When the right angle is divided into two equal parts each angle measures 45°.

What kind of angle is 47 degrees?

What is 90-degree angle look like?

A 90 degrees angle always corresponds to a quarter turn. Rectangle and square are the basic geometric shapes that have a measurement of all four angles as 90 degrees. When two lines intersect each other and the angle between them is 90-degree then the lines are said to be perpendicular.

What angle is 75?

Answer: acute angle-an angle between 0 and 90 degrees.

What angle is 91?

obtuse anglesSince obtuse angles are angles with a measure larger than 90°, the smallest integer obtuse angle will have a measure of 91°.

What angle is between 90 and 180?

obtuse anglesAngles between 90 and 180 degrees (90°< θ <180°) are known as obtuse angles. Angles that are 90 degrees (θ = 90°) are right angles.

What type of angle is 48 degrees?

acute angle-an angle between 0 and 90 degrees. right angle-an 90 degree angle. obtuse angle-an angle between 90 and 180 degrees.

What type of angle is 117?

Solution: Option (b) – 117° and option (c) – 121° are more than 90° and less than 180°. Therefore, they are obtuse angles. Therefore, 117° and 121° are obtuse angles.
