This can only be solved with the information given if we regard ∆ABC as a right angled triangle.
If AC is the hypotenuse then Sin c = 2/11 = 0.181818 therefore angle c = 10.48°
If AC is not the hypotenuse then Tan c = 2/11 = 0.181818 therefore angle c = 10 .30°

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
Assume abc def if df equals 12 ef equals 7 and ab equals 17 what is the length of de?
17
A plus B plus C equals AB?
i think its ABC and if that not right ask a teacher for the answer
Side ac equals 12 side bc equals 16 and side ab equals 20 is triangle abc a right triangle?
yes
In line segment Ac is perpendicular to line segment CB and the measurement of angle CBD equals 125 degrees the the measurement of angle A equals?
The problem is meaningless without a diagram but I am guessing that ABC make a triangle and D is on the extension of AB beyond B. In that case we use the exterior angle theorem to get CBD = C + A, so 125 = 90 + A and A = 35.
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.
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
What angle is included by the segments ab and bc?
Angle abc.
How can you identify a figure that has sides ab and ac of triangle abc when angle a equals angle c?
This is called an isoceles triangle. An isoceles triangles is when two angles equal.
Do angles abc make a right angle?
Angle abc will form a right angle if and only if, segment ab is perpendicular to segment bc.
Given triangle ABC angle B is 38 degrees angle c is 56 degrees and BC equals 63 cm find the length of AB?
52.4 cm
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)
How do you show that ab plus ab plus cc equals abc?
If, as is normal, ab represents a times b, etc then ab + ab + cc = 2ab + c2 which is generally not the same as abc.
When ab is perpendicular to CD?
when angle abc and abd equalls to 90 degree then ab perpendicular to cd
What are congruence theorems and postulates?
If the sides AB, BC and CA of triangle ABC correspond to the sides DE, EF and FD of triangle DEF, then the two triangles are congruent if:AB = DE, BC = EF and CA = FD (SSS)AB = DE, BC = EF and angle ABC = angle DEF (SAS)AB = DE, angle ABC = angle DEF, angle BCA = angle EFD (ASA)If the triangles are right angled at A and D so that BC and EF are hypotenuses, then the triangles are congruent ifBC = EF and AB = DE (RHS)BC = EF and angle ABC = angle DEF (RHA).
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.
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)
