Abc is a right angled triangle ac equals 6cm bc equals 9cm work out the length of ab give your answer to 3 sig figures?
If angle ACB is the right angle then ab is the hypotenuse. Then, (ab)2 = 62 + 92 = 36 + 81 = 117 ab = √117 = 10.8 (3 sf) If angle BAC is the right angle then ab is one leg of a right angled triangle with bc the hypotenuse. 92 = 62 + (ab)2 : (ab)2 = 92 - 62 = 81 - 36 = 45 ab = √45 = 6.71 (3 sf)
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
In triangle abc ab equals 2 and ac equals 11 what is angle c it is a right triangle?
It can be but need not be.
In circle O the area of the sector with central angle AOB is 30 pi cm squared and radius OA is 6 cm. What is the angle measure of arc AB and the length of AB?
The area of the whole circle is PI x 6 squared which equals 36 PI. We can now use the ratio 30/36 = x/360 to find the angle (360 is the full angle if the circle, x is the angle of the segment, pi's cancell out) If we solve for x we get 300 degrees which is the angle we need. As for the length, the circles circumference is 12 PI (12 is the diameter). This means that 30/36= AB/12PI AB=10PI
ABCDEFGHJK is a regular decagon sides AB and DE are extended so that they meet at point L in the exterior of the polygon find the measure of angle of angle BLD?
angle BLD is 72 degrees.
