Question

triangle ABC is right angle at a is draw perpendicular to BC if ab is equal to 5 cm and ac is equal to 12 cm find the area of triangle abc also find the length of a d​

Answer 1

Answer:

Area of ABC = 30 cm² and AD = 4.61cm

Step-by-step explanation:

Area of ABC

=1/2 × AC × AB

=0.5 × 12 × 5

=30 cm²

By Pythagoras Theorem,

(AC)² + (AB)² = (BC)²

(12)² + (5)² = (BC)²

(BC)² = 144 + 25

(BC)² = 169

BC = 13 cm

Area of ABC = Area of ABC

30 = 1/2 ×AD ×BC

60 = AD × 13 (Multiplying by 2 on both the sides)

AD = 60/13

AD = 4.61 cm
