Lady_Fox [76]

Calculation of x:

we can see that

x is hypotenuse

so, we can use pythagoras theorem

$x=\sqrt{8^2+10^2}$

$x=2\sqrt{41}$

Calculation of y:

we can use tan formula to find it

opposite=8

adjacent=10

$tan(y)=\frac{8}{10}$

$y=tan^{-1}(\frac{8}{10})$

$y=38.65degree$

Calculation of z:

we know that sum of all angles of any triangle is 180

$y+z+90=180$

$z=51.35degree$ ...........Answer

EASY AND BRAINLIEST!!!!

Answer:

$6x-4y=15$

Step-by-step explanation:

step 1

Find the slope of line L

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal

In this problem we have

$2x + 3y = 5$

Isolate the variable y

$3y = -2x+5\\y=-(2/3)x+(5/3)$

The slope of the given line is

$m=-2/3$

The slope of the Line L is

$m=3/2$

step 2

Find the x-intercept of the line

$2x + 3y = 5$

The x-intercept is the value of x when the value of y is equal to zero

For y=0

$2x + 3(0) = 5\\x=5/2$

The x-intercept is the point (5/2,0)

step 3

Find the equation of the line L

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=3/2\\point (5/2,0)$

substitute

$y-0=(3/2)(x-5/2)$

$y=(3/2)x-(15/4)$

Convert to standard form

AX +By+C

where

A is a positive integer

B and C are integers

Multiply both sides by 4

$4y=6x-15\\6x-4y=15$

Jon caught four fish that weighed a total of 252 pounds.The kingfish weighed twice as much as the amberjack and the white marlin

fenix001 [56]

1 Amberjack
Kingfish equals 2 Amberjacks
Marlin equals 2 Kingfish or 4 Amberjacks
Tarpon equals 5 AmberJacks

So:
1A plus 2A plus 4A plus 5A equals the 252.
(where A is weight of the AmberJack).

Therefore:
12A equals 252, and A is 21. (252/12 = 21)

Then:
The Amberjack is 21Ibs.
The Kingfish (twice as much as A) is 42Ibs.
The Marlin (four times A) is 84Ibs.
And the Tarpon (five times A) is 105Ibs.

To Check:
21 + 42 + 84 + 105 = 252
