Answer 1

Answer:

1) The angle is 25°

Let the required angle be x°

Complementary angle with respect to x° is

(90 - x)°

Supplementary angle with respect to x° is

(180 - x)°

Given that,

7(90 - x) = 3(180 - x) - 107(90−x)=3(180−x)−10

630 - 7x = 540 - 3x - 10630−7x=540−3x−10

100 = 7x - 3x100=7x−3x

4x = 1004x=100

⇒x=25°

Therefore, the required angle is 25°

2)Using the Heron’s formula to solve the problem:

a = 150 cm

b = 120 cm

c = 200 cm

Perimeter, P = 150 + 120 + 200 = 470

Semi-perimeter, S = 470/2 = 235

Area = √ ( S)° (S - a)° (S - b)° (S - c) )

Area = √ ( 235)° (235 - 150)° (235 - 120)° (235 - 200) )

Area = √ ( 235)° (85)° (115)° (35) )

Area = √ (80339375)

Area = 8,966.57 cm²
