What angle is included by the segments ab and bc?
Angle abc.
What words describe a triangle?
The definition of a triangle is the union of segments AB, BC, and AC (where A, B, and C are not all collinear).
In triangle ABC BC equal 4cm M is the midpoint of BC AM equals 4cm and angle AMB equals 120 degrees calculate AC AB and angle ACB?
AC = 2*sqrt(3) = 3.4641AB = 2*sqrt(7) = 5.2915 angle ACB = 90 degrees.
If AB 34 and AC 12 find the length of BC round to the nearest tenth.?
Assuming that AB and AC are straight lines, the answer depends on the angle between AB and AC. Depending on that, BC can have any value in the range (22, 46).
Can you draw an obtuse scalene triangle?
Draw two lines AB and AC that meet at point A. The angle BAC is greater than 90° but less than 180°. Let AB > AC. Draw a third line BC to complete the triangle so that BC is not equal to AB or AC. The triangle is a scalene triangle containing an obtuse angle.
What angle is included by the segments ab and bc?
Angle abc.
Why are there six trigonometrics functions only?
All the trigonometric functions are derived from the right angled triangle. If we consider the three sides (AB, BC, CA) of a triangle and the included angle. There is a possibility of getting six functions based on the ratios like AB/AC, BC/AC, AB/BC, BC/AB, AC/BC, AC/AB . So we will have six trigonometric functions
Bc is included between?
Angle B and Angle C
What are the consinetagent and sine?
Consider a right triangle ABC as shown below. The right angle is at B, meaning angle ABC is 90 degrees. With the editor I have, I am not able to draw the line AC but imagine it to be there. By pythagorean theorem AC*2 = AB*2 + BC*2. The line AC is called the hypotenuse. Consider the angle ACB. The cosine of this angle is BC/AC, the sine is AB/AC and tangent is AB/BC. If you consider the angle BAC, then cosine of this angle is AB/AC, the sine is BC/AC and tangent is BC/AB. In general sine of an angle = (opposite side)/(hypotenuse) cosine of an angle = (adjacent side)/(hypotenuse) tangent of an angle = (opposite side)/(adjacent side) |A | | | | | | |______________________C B
Can you name 4 line segments?
Yes. AB, AC, BC and EF.
What is a tringle?
The union of the segments AB, BC, and AC of three nonlinear points A, B, and C.
If the area of triangle ABC is 27cm2 BC is 12cm and angle BCA is 98 degrees what is length AC?
Area = 1/2*a*b*sin(C) where a = BC, b = AC and angle C = angle BCA 27 = 0.5*12*AC*sin(98) So AC = 27/[0.5*12*sin(98)] = 4.54 approx.
How do you prove the hinge theorem?
If of triangle ABC and A'B'C' sides AB = A'B' and AC = A'C', and the included angle at A is larger than the included angle at A*, then BC > B'C'.Proof:A A'/|\ /|/ | \ / |/ | \ / |/ | \ B'/ |B | X \C |C'DWe construct AD such that AD = A'C' = AC and angle BAD = angle B'A'C'.Triangles ABD and A'B'C' are congruent. Therefore BD = B'C'.Let X be the point where the angle bisector of angle DAC meets BC.From the congruent triangles AXC and AXD (SAS) we have that XD = XC.Now, by the triangle inequality we have that BX + XD > BD, so BX + XC > BD, and consequently BC > BD = B'C'.
What words describe a triangle?
The definition of a triangle is the union of segments AB, BC, and AC (where A, B, and C are not all collinear).
In right ABC AC equals 4 cm and BC equals 6 cm What is the area of the triangle?
It can be anything between zero and infinity, depending on the angle between AC and BC.
In triangle ABC BC equal 4cm M is the midpoint of BC AM equals 4cm and angle AMB equals 120 degrees calculate AC AB and angle ACB?
AC = 2*sqrt(3) = 3.4641AB = 2*sqrt(7) = 5.2915 angle ACB = 90 degrees.
If AB 34 and AC 12 find the length of BC round to the nearest tenth.?
Assuming that AB and AC are straight lines, the answer depends on the angle between AB and AC. Depending on that, BC can have any value in the range (22, 46).
