Question

. Angles A and B of
a ∆ABC are 30° and
6o°. Write which of the following is true?
a. AB² + BC² = AC^
b. AB²+ AC² = BC ²
C AC² + BC²= AB²​

Answer 1

Answer:

C. AC^2+BC^2=AB^2

Step-by-step explanation:

angle A + angle B = 30°+60° =90°

So angle C = 180°-90° = 90°

So ABC is a right angled triangle

According to pythagorean theorem AC^2+BC^2 = AB^2
