An angle measures the amount of turn. Names of Angles. As the Angle Increases, the Name Changes Be Careful What You Measure. The smaller angle is an Obtuse Angle , but the larger angle is a Reflex Angle. So when naming the angles make sure that you know which angle is being...Ratings 96% (108) 104 out of 108 people found this document helpful. This is a preview.

Get the right answer, fast.ABC is a right-angled triangle, having the right angle at B, such that BC = 6 cm and AB = 8 cm. How do I find the radius of its incircle? If H and O are If BD=3cm & DC=2cm and the area of the triangle is x cm square, what is the value of x? Triangles ABC is a equilateral triangle and triangle CDE is a...In the right triangle ABC below, what is the cosine of angle A? . Solution We first find the hypotenuse BA and use it to find cos(A). BA = √(32 + 42) = 5 cos(A) = adajacent side The measures of angles A, B and C of a triangle are in the ratio 3:4:5. What is the measure, in degrees, of the largest angle?

In ABC C is a right angle what is the measure of x | Course Hero

The more familiar unit of measurement is that of degrees. A circle is divided into 360 equal degrees, so that a right angle is 90°. For the time being, we'll only Then the angle cuts off an arc of the circle, and the length of that arc is the radian measure of the angle. It is easy to convert between degree...For the $$ m\overparen{ABC} $$ ? to equal ¾ the total measure of the circle's circumference , what must be the value of X? Circle 1 is the only circle whose intercepted arc is half the measure of the angle between the chord and the intersecting line.As ABC is a right angled triangle, it means , they cannot be both 90 degrees, So Measure of ∠ABC. ∠ A B C.A Straight angle measures 180o. Congruent angles are angles that have the same measure. ∠ABC ≅ ∠DEF the angles are congruent m∠ABC = m∠ Perpendicular Bisector of a line forms right angles and bisects the line segment. The Distance from a point to a line is the length of the perpendicular...

A right triangle has side lengths AC = 7 inches, BC = 24 inches, and AB = 25 inches. What are the measures of the angles in triangle ABC? The measure of angle BAC can be calculated using the equation sin-1 (3.1/4.5) = x. What is the measure of angle BAC?2. The measure of any angle, when the measure of the three sides of a triangle ABC are known. Classification of Triangles According to anglesIf one angle of a triangle is a right angle (90°), then it is called a Right triangle.Find the radius of the incircle of $\triangle ABC$. See the following image : The center of the incircle will be the intersection of the angle bisectors shown. And the find the x coordinate of the center by solving these two equationsMeasuring Angles and Arcs. Why? The thirteen stars of the Betsy Ross flag are arranged equidistant from Its sides contain two radii of the circle. ∠ABC is a central angle of ⊙B. A central angle separates the circle into two arcs with measures related to the measure of the central angle.Right triangles have one angle which measures 90 degrees, and two other angles whose sum is 90 degrees. The side opposite the right angle is called Example: In right triangle ABC with right angle C, if AB = 12 and AC = 8, find BC. 1. Special Triangles. In a 30o − 60o − 90o triangle, the lengths of...

If you can use a calculator, you'll use any inverse trig function to get the precise answer and fit it to the choices.

But this is just a a couple of selection question.

Just take a look at the picture!

It's clearly more than 45 degrees. That's transparent from the means the triangle is drawn, and confirmed since the opposite side is greater than the adjacent side. Only one of the answers is > 45, so it should be 64.8.

No want to even calculate the precise value if this is just a more than one choice take a look at. Just get rid of the unimaginable answers--that's the quickest way.
