In the right angle triangle abc what is the length of ac if ab equals 22 cm and bc equals 32 cm?
you use Pythagoras theorem. Square of the Hypotenuse = square of the other 2 sides i.e ac squared = ab squared + bc square = 22 Squared + 32 Squared = 484 + 1024 = 1508 so ac = square root of 1508 = 38.83 cm(2 d.p)
If the measure of angle A is 30° and AC=18,find the length of AB?
36/√3
What would a triangle look like if ab plus ac equals bc?
It would be a straight line of length bc
What is length ab if cab is 90 degrees and ac is 9cm and bc is 15cm on right angle triangle?
12 cm
What is the length of the shortest side of abc whose perimeter is 64 units if the ratio abbc is 43 and ac is 20 less than the sum of the lengths of sides ab and bc?
ab 4
Quadrilateral abcd is a square bc equals 10 what is the length of ac?
If the quadrilateral is a square then all of its sides are the same length. ac is not one of the sides but is a diagonal which forms the hypotenuse of a right angle triangle with sides ab and bc. According to Pythagoras the sum of the square of the hypotenuse is equal to the sum of the squares of the other two sides. As side ab measures 10 then 10 squared = 100. Side bc has the same measurements. The square of side ac must equal 200 (100 + 100) so the length of side ac must equal the square root of 200 (100 + 100) which is 14.14 (to 2 decimal places).
Quadrilateral abcd is a square bc equals 2 what is the length of ac?
\8
What are two segments that have the same measurement?
If 2 segments have the same length they are known as 'congruent segments' IE: segment AB=segment AC (or AB=AC) then AB @ AC (or AB is congruent to AC)
In the right angle triangle abc what is the length of ac if ab equals 22 cm and bc equals 32 cm?
you use Pythagoras theorem. Square of the Hypotenuse = square of the other 2 sides i.e ac squared = ab squared + bc square = 22 Squared + 32 Squared = 484 + 1024 = 1508 so ac = square root of 1508 = 38.83 cm(2 d.p)
If parallelogram ABCD is a square then AB will equal AC?
never
What is the length of the hypotenuse AC?
sqrt(ab^2 + bc^2)
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).
How do you prove that In a quadrilateral ABCD prove that AB plus BC plus CD plus DA 2( AC plus BD )?
You cannot prove it since it is not true for a general quadrilateral.
If the measure of angle A is 30° and AC=18,find the length of AB?
36/√3
If d is the midpoint of ac and c is the midpoint of bd what is the length of ab if bd is 12cm?
16cm
In the given right triangle find the length of the hypotenuse AB if BC 6 and AC 5.?
The length is sqrt(61) units.
How do i find length of AB in the triangleABC angleB equals 95 degrees angleC equals 24 degrees and line AC equals 17cm how do i find the length of AB?
By use of the sine rule: sin A / BC = sin B / AC = sin C / AB Angles B and C are known, as is length AC, so: sin B / AC = sin C / AB AB = AC x sin C / sin B AB = 17cm x sin 24 / sin 95 ~= 6.94cm The ratios for the sine rule can also be given the other way up: BC / sin A = AC / sin B = AB / sin C (I learnt the rule the first way.) Further, if r is the radius of the triangle's circumcircle, then: sin A / BC = 1/2r or BC / sin A = 2r
