SINCE THATS AN ISOSCELES TRIANGLE:

AB=BC

SO 3x-4=5x-10

But we have to find x

3x-4=5x-10

Minus 3x on both sides

-4=2x-10

Add 10 on both sides

6=2x

Divide 2 on both sides

3=x

So x is 3

Now since we are looking for side AB which is 3x-4

Substitute in 3 as x

3(3)-4

9-4=5

So 5 is the answer.

Brainlist would be much appreciated!

john currently has enough money to buy 45 books. If the cost of each book was 10 cents less.john could buy 5 more books. How muc

SVEN [57.7K]

Let the cost of one book= x cents
Let the money john have= y cents

According to the question,

45x=y ...eq(1)
(45+5)(x-5)=y
50(x-5)=y
50x-250=y ...eq(2)

On subtracting (1) from (2).
(50x-250)-45x=y-y
5x-250=0
x=250/5
x=50

Thus, cost of each book is 50 cents and john has 2250 cents.

Hope it helps.
Don't feel shy in saying thx if it helps.

A line with a negative slope and a negative

Alina [70]

Answer:

<h2>First quadrant will the line not pass.</h2>

Step-by-step explanation:

The given line has a negative slope. It means with increasing value of x, y will be decreasing. It has a negative y-intercept that is at x = 0, y is less than 0.

If the value of x will be greater than 0, the value of y will be going downwards continuously.

If x > 0, y < 0, as the line has a negative y-intercept.

A point in first quadrant means x > 0 as well as y > 0.

Hence, the line cannot pass through the first quadrant.

Given that tangent theta = negative 1, what is the value of secant theta, for StartFraction 3 pi Over 2 EndFraction less-than th

vivado [14]

The value of tangent theta is equal to the negative 1. At this value the value of secant theta is $\sqrt{2}$ .

<h3>What is tangent theta?</h3>

The tangent theta in a triangle is the ratio of sine theta and cos theta. It can be written as,

$\rm tan\theta=\dfrac{sin \theta}{cos \theta}$

Given information-

The value of tangent theta is equal to the negative 1.

$\tan \theta=-1$

The tangent theta in a triangle is the ratio of sine theta and cos theta. It can be written as,

$\rm tan\theta=\dfrac{sin \theta}{cos \theta}$

The value of tangent theta is equal to the negative 1. Thus put the value in above expression as,

$\rm -1=\dfrac{sin \theta}{cos \theta}\\$

Simplify it further as,

$\rm -cos \theta=sin \theta$

When the value of cosine and sine theta is equal, then the angle exist in 4th quadrant with the value of $\dfrac{7\pi}{4}$ . Which extent to the $\sqrt{2}/2$ for the cosine function.

In the trigonometry cosine theta is the reciprocal of the secant theta. Thus,

$\rm \dfrac{1}{sec\theta}=\dfrac{\sqrt{2}}{2}\\sec\theta=\sqrt{2}$

Thus the value of secant theta is $\sqrt{2}$
