What else can I help you with?
In triangle ABC side AB is 9 cm shorter than side AC while bc is 3cm longer than side AC if the perimeter is 48 cm find the lenghts of the three sides?
AB + AC + BC = 48 AB + (AB +9) + (AB + 9 + 3) = 48 Solve and AB = 9 So AB = 9, AC = 18 and BC = 21
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
How to check in the triangle abc side ab is 2 cm shorter than side ac while side bc is 1cm longer than ac if the perimeter is 62cm find the lengths of the three sides?
draw it out for ease. data: ab + 2 = ac bc-1 = ac therefore ab +2 = bc - 1 ab - bc = -3 perimeter is 62. /3 as most values are small difference. average distance is ~21. ab is smallest, guess it is 19. if so, ac would be 21. bc would be 22. does this add up? it actually does. i guess there is a mathematical way of doing this other than trial and error like the way i just did it, but i cannot see it right now
Why can't a triangle have parallel sides?
For two sides to be parallel they must not meet at a point (vertex). A triangle has only 3 sides. Let the vertices of a triangle be ABC; then the 3 sides of the triangle are AB, AC and BC. The sides AB and AC meet at vertex A, so they cannot be parallel. The sides AB and BC meet at vertex B, so they cannot be parallel. So Side AB is not parallel to AC (meets at vertex A) and not parallel to BC (meets at vertex B). The only possibility left is that side BC is parallel to side AC. But the sides BC and AC meet at vertex C so they cannot be parallel. Thus none of the sides of a triangle can be parallel.
If triangle ABC is equilateral and side AB measures 15 cm what does side BC measure?
15 cm
Triangle abc is a right triangles if side ac 7 and side bc 10 what is the measure of side ab?
149
In triangle ABC side AB is 9 cm shorter than side AC while bc is 3cm longer than side AC if the perimeter is 48 cm find the lenghts of the three sides?
AB + AC + BC = 48 AB + (AB +9) + (AB + 9 + 3) = 48 Solve and AB = 9 So AB = 9, AC = 18 and BC = 21
Triangle abc is a right triangle if side ac equals 7 and side bc equals 10 what is the measure of side ab?
12
If ab plus bc equals ac then ac equals ab plus bc?
yes because ab plus bc is ac
Triangle abc is a right triangle. If side AC equals 5 and side AB equals 10 what is the measure of side BC?
9_or_yes">9 or yesA+ = 12
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
Triangle abc is a right triangle if side ac equals 5 and side bc equals 6 what is the measure of side ab?
If CB is the hypotenuse, then AB measures, √ (62 - 52) = √ 11 = 3.3166 (4dp) If AB is the hypotenuse then it measures, √ (62 + 52) = √ 61 = 7.8102 (4dp)
How long is side ac when side ab is 6 and side bc is 8 in a triangle?
If it's a right angle triangle then side ac is 10 units in length.

Triangle ABC is a right triangle. If side AC is 7 units and side BC is 10 units what is the measure of side AB?
By using Pythagoras' theorem for a right angle triangle if side AB is the hypotenuse it is the square root of 149 which is about 12.207 rounded to three decimal places
Calculate the measure of angle A in each triangle to 1 decimal place. S?
Note!!!! ignore the S at the end these are the questions 1. side AC= 31 cm, side BC= 20 cm and angle B= 58 degrees 2. side AC= 21 cm, side BC= 28 cm and side AB= 32 cm 3. side AC= 8 cm and side AB= 10 cm please help last 3 questions of my homework. My teacher collects it =(
What is BC if AC is 5 and AB is 8?
AC=5 AB=8 A=1 B=8 C=5 BC=40
