Answer:

x = 4

Step-by-step explanation:

7x - 3 = 5x + 5 --> 7x - 5x = 5 + 3 --> 2x = 8 --> x = 4.

You can check by substitute x = 4 back to the original equation.

k0ka [10]

Answer:

Option (3)

Step-by-step explanation:

By applying cosine rule in the triangle ABC,

BC² = AC² + AB² - 2(AC)(AB)cosA

5² = 3² + 7²- 2(3)(7)cosA

25 = 9 + 49 - 42cos(A)

25 = 58 - 42cos(A)

cos(A) = \frac{33}{42}

A = \text{cos}^{-1}\frac{11}{14}

A = 38.21°

A ≈ 38°

Option (3) will be the correct option.
