Question

Abc is right angled at

b. If m a = 30. What is the length (in cm) of ab, if ac = 8 cm?

Answer 1

Answer:

MAY IT HELP YOU,

Step-by-step explanation:

in a right angled triangle abc,

∠ABC=90°

∠A=30°

∠C=60°----(REMAINING ANGLE).

ΔABC IS an right angled triangle.

by theorem of 30° -  60° -90°Δtheorem,

AB=√3/2 ×Hypotenuse._______ ( side opp. to 60°)

AB=√3/2×AC

AB=√3/2×8

AB=4√3 CM.

∴AB=4√3 cm
