JEE Main

Q. In triangle ABC, if angle A = 45 degrees and angle B = 45 degrees, what is the relationship between sides a, b, and c?

A. a = b
B. a > b
C. a < b
D. a + b = c

Solution

In an isosceles triangle with angles A and B equal, the sides opposite those angles are equal, hence a = b.

Correct Answer: A — a = b

Q. In triangle ABC, if angle A = 45 degrees and angle B = 45 degrees, what is the type of triangle?

A. Scalene
B. Isosceles
C. Equilateral
D. Right

Solution

Since two angles are equal, triangle ABC is isosceles.

Correct Answer: B — Isosceles

Q. In triangle ABC, if angle A = 45 degrees and side a = 10 cm, what is the length of side b if angle B = 60 degrees?

A. 8.66 cm
B. 10 cm
C. 12.25 cm
D. 15 cm

Solution

Using the Law of Sines: a/sin(A) = b/sin(B). Therefore, b = a * (sin(B)/sin(A)) = 10 * (sin(60)/sin(45)) = 10 * (√3/2)/(√2/2) = 10 * √3/√2 = 10 * √(3/2) = 8.66 cm.

Correct Answer: A — 8.66 cm

Q. In triangle ABC, if angle A = 45° and angle B = 45°, what is angle C?

A. 45°
B. 60°

Solution

Using the Law of Sines: b/a = sin(B)/sin(A) => b = a * (sin(B)/sin(A)) = 10 * (√3/2)/(√2/2) = 10 * √3/√2 = 10 * 8.66/10 = 8.66.

Correct Answer: A — 8.66

Q. In triangle ABC, if angle A = 60 degrees and angle B = 70 degrees, what is angle C?

A. 50 degrees
B. 60 degrees
