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.
Ad equals 10 units ab equals 8 units ac equals 12 units ed equals 4.5 units if angle equals 50 degrees what is the measure of angle bcd?
For you A+ Cheaters ;D it's 50!
To the nearest degree find the measure of angle b in triangle abc given measure of angle a equals 48degrees ac equals 62cm and ab equals 61cm?
67 degrees
Which is the measure of line segment of AB if AC equals 10?
The answer is "No Solution" because there is not enough information.
What is the measures of angle x if angle b equals 85 and side ab equals 17?
More information is needed.
Triangle abc is a right triangle if side ac equals 7 and side bc equals 10 what is the measure of side ab?

In trapezoid abcd ab is parallel to CD then is measure of angle an equal to the measure of angle d?
No. But they add up to 180 degrees.
If you have a circle and the measure of the arc AB equals 80 and the measure of arc CE equals 16 which is the measure of EDC?
32 degrees
Triangle abc is a right triangle if ac equals 7 and side bc equals 10 what is ther measure of side ab?
The square root of 149 (7 squared plus 10 squared equals 149).
