Answer:

Step-by-step explanation:

Because the two angles are shown are equal, an equation can be made and solved:

8t+1= 97

To solve subtract 1 from both sides:

8t= 96

Then divide:

t= 12

Hope this helps!

Can someone PLEASE help me solve this equation ? due soon

RideAnS [48]

$\sf{Given : 3tanx + 7 = \dfrac{2}{(1 - sinx)(1 + sinx)}}$

We know that : (a - b)(a + b) = a² - b²

$\implies \sf{3tanx + 7 = \dfrac{2}{1 - sin^2x}}$

We know that : 1 - sin²x = cos²x

$\implies \sf{3tanx + 7 = \dfrac{2}{cos^2x}}$

$\sf{\bigstar \ \ We \ know \ that : \boxed{\sf{\dfrac{1}{cos^2x} = sec^2x}}}$

$\implies \sf{3tanx + 7 = 2sec^2x}$

We know that : sec²x = 1 + tan²x

$\implies \sf{3tanx + 7 =2(1 + tan^2x)}$

$\implies \sf{2 + 2tan^2x - 3 tanx - 7 = 0}$

$\implies \sf{2tan^2x - 3 tanx - 5 = 0}$

$\implies \sf{2tan^2x - 5tanx + 2tanx - 5 = 0}$

$\implies \sf{2tanx(tanx + 1) - 5(tanx + 1) = 0}$

$\implies \sf{(tanx + 1)(2tanx - 5) = 0}$

$\implies \sf{tanx = -1 \ (or) \ tanx = \dfrac{5}{2} }$

What is the correct answer i have to type in the yellow boxes?

sertanlavr [38]

Answer:

(-10)²= -10 × -10 = 100

Step-by-step explanation:

When any number is squared whether it is positive or negative, the result will always be positive:

Anything squared means the number multiplied by itself:

So:

(-10)²= -10 × -10 = 100

In a 45-45-90 triangle, the ratio of the length of the hypotenuse to the length of a side is

mestny [16]

<h2>Explanation:</h2>

See the figure below for a better understanding of the problem. Since we have a 45-45-90 triangle, this is an isosceles triangle, so both the adjacent and opposite sides measure the same value, say, x. Then the hypotenuse would be:

$H=\sqrt{x^2+x^2} \\ \\ H=2\sqrt{2}$

Then. the ratio of the length of the hypotenuse to the length of a side is:

$\boxed{r=\frac{2\sqrt{x}}{x}}$
