How to solve it? I dont know the solving ways

6.2 cm

Step-by-step explanation:

Apply the Law of cosines, given as:

c² = a² + b² - 2ab×Cos(C)

Where,

a = 4 cm

b = 8 cm

c = AB = ??

C = 50°

Plug in the value into the equation

c² = 4² + 8² - 2*4*8*Cos(50)

c² = 16 + 64 - 64*Cos(50)

c² = 80 - 64*Cos(50)

c² = 38.861593

c = √38.861593

c = 6.2 cm (nearest tenth)

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
