3. In a right angled Delta*A * B * Q , angle B=90^ , angle Q=30^ and AQ = 8 cm . Find AB.
Answers
Answer:
In triangle ABC, angle A=90°, angle B=30°, BC=8cm. Find the length of side AB and AC?
With TrianCal, AB ≈ 6.93 cm and AC = 4 cm.
In triangle ABC, measure of angle B=90° , measure of angles C=30°. If AC=36, then what are AB and BC?
In triangle ABC, angle B=90°, angle C=60°, BC=8cm. What is side AB and AC?
In a triangle ABC, angle B=90, angle C=60, angle A=30 and BC=12cm. What is the area of the triangle?
△ABC has ∠ABC = 90° and ∠ACB = 30°. If a point inside the triangle is chosen at random, what is the probability that it is nearer to AB than to AC?
ABCD is a kite whose angle A=90°, angle C=60°, and the length of side AB is 6 cm. What is the value of side AC?
Hi,
For any triangle, The sum of all three angles is 180 degree. In this example, A = 90 degree and B = 30 degree. So, C= 180 - 90 -30 = 60 degree.
AB is the opposite side for the angle C and AC is the opposite side for the angle B.
Sin 30 = AC / BC as BC is the opposite for the angle 90 degree and it is hypotenuse.
AC => BC * sin 30 => 8 * 1/2 = 4 CM
Sin 60 = AB / BC as BC is the opposite for the angle 90 degree and it is hypotenuse.
AB => BC * sin 60 => 8 * 1.732 / 2 => 6.928 CM
