CAN SOLVE​

Answer 1

Answer:

1) Option c

2) Option c

3) Option d

4) Option a

5) 10 cm²

6) 54 cm²

Step-by-step explanation:

1) By Pythagoras theorem,

13² = 5² + (Adj)²

169 - 25 = (Adj)²

144 = (Adj)²

Adj = √144

Adj = 12

Area of Δ = 1/2 × b × h

b = 5cm

h = 12cm

Area of Δ = 1/2 × 5 × 12

Area of Δ = 30 cm²

∴ The correct answer is option C

2) Since ∠ABE = 20 cm²

Then, ∠ABC = 2 × (∠ABE) because ∠ABE divides the ∠ into two parts equally.

 ∴    = 2 × (∠ABE)

       = 2 × 20

       = 40 cm²

∴ The correct answer is option c

3) Area of Scalene Δ = b × h

   = 7 × 9

   = 63 cm²

∴ The correct answer is option d

4) 11 cm

∴ The correct answer is Option a

5) Area of Δ = 1/2 × b × h

= 1/2 × 5 × 4

= 10 cm²

6) Area of Δ = 1/2 × h × h

= 1/2 × 9 × 12

= 54 cm²
