ABCD is a rectangle. if AC = 3y/5 anf BD= 3(y-4), find the length of each diagonal

1 answer:

3 0

Remember please that Diagonals of a Rectangle are equal to each other:<span> 3y/5 = 3(y-4)
So
</span><span>3y = 15(y-4)
3y = 15y - 60
60 = 12y
y = 5 Diagonals are both 3 units
With that you will be able to know which is the answer from your options</span>

Answer:

The answer is

$\huge y = 3x + 21$

Step-by-step explanation:

To find an equation of a line given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

where

m is the slope

( x1 , y1) is the point

From the question the point is (−5, 6) and slope = 3

The equation of the line is

$y - 6 = 3(x + 5) \\ y - 6 = 3x + 15 \\ y = 3x + 15 + 6$

We have the final answer as

$y = 3x + 21$

Hope this helps you

Can someone help me solve these three problems please??

Tasya [4]

I'll solve 21, and you then should be able to solve the rest on your own!

Since ADC is 135, that means that that whole angle is 135 degrees. In addition, since angles ADB and BDC add up to ADC, we get ADB+BDC=ADC=135=11x+9+7x=18x+9. Subtracting 9 from both sides, we get 126=18x. Dividing both sides by 18, we get x=7. Plugging that into 11x+9=BDC, we get 11*7+9=77+9=86
