Answer:

Step-by-step explanation:

Given the 2 equations

y = 3x + 3 → (1)

y = - 2x + 3 → (2)

Substitute y = 3x + 3 into (2)

3x + 3 = - 2x + 3 ( add 2x to both sides )

5x + 3 = 3 ( subtract 3 from both sides )

5x = 0 , then

x = 0

Substitute x = 0 into (1)

y = 3(0) + 3 = 0 + 3 = 3

solution is (0, 3 ) → A

Answer: $\text{tan a}= \frac{3\sqrt{91} }{91}$

Step-by-step explanation:

Since, in the triangle abc,

ab = 10√91 unit, bc = 30 unit, ca = 100 unit and m∠b = 90°

⇒ $\text{tan a} = \frac{bc}{ab}$

⇒ $\text{tan a} = \frac{30}{10\sqrt{91}}$

⇒ $\text{tan a} =\frac{3}{\sqrt{91}}$

⇒ $\text{tan a} = \frac{3\times \sqrt{91}}{\sqrt{91}\times \sqrt{91}}$

⇒ $\text{tan a} = \frac{3\sqrt{91}}{91}$

Which is the required value of tan(∠a).
