Montano1993 [528]

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).

❌what number would you have to add to both sides to complete the square?

Verdich [7]

Hello,

Let's to remember,

To the perfect square:

X^2 +12x = -6

We would have to add 6^2

Because,

X^2 + 2.(6X) = -6

As (x+k) = x^2 +2xk +k

And,

2xk = 2.6x

xk = 6x

K = 6

Then,

(X+k)^2 = x^2 + 2xk+k^2

= x^2+2.x.6+6^2

= x^2+6x+36

We would to add 36, and would stay:

X^2 + 6X = -6

x^2 +6x + 36 = -6 +36

X^2 +2.6x +6^2 = 30

(X+6)^2 = 30

Answer is the letter A)

A = P (1 + r/n)^nt
A = 1,349.34(1+0.1366/12)^12
A = 1545.65

answer: he will owe $1545.65 after one year
