Question

plz solve the answer​

Answer 1

Answer:

AC=10cm

Step-by-step explanation:

as it is a 30°-60°-90° triangle,

side opp to 30° angle is 1/2 of the hypotenuse

Therefore, side opp to angle ACB is 5cm

therefore hypotenuse = 5×2

=10 cm

Therefore, AC=10cm

Gɪᴠᴇɴ ᴛʜᴀᴛ ɪɴ ∆ABC,

∠B = 90°, AB = 5cm , ∠ACB = 30°

➜ sin 30° = ᴏᴘᴘᴏsɪᴛᴇ / ʜʏᴘᴏᴛᴇɴᴜsᴇ

➜ sin 30° = AB / AC

➜ 1/2 = 5/AC

➜ AC = 10cm
