4 over 3.2 and 6 over 4.8
Ray Of Light [21]3 years ago
4 0

Answer:

\frac{4}{10} =\frac{3.2}{8}

Step-by-step explanation:

Given : AD=4

           DB=6

           AE=3.2

           EC=4.8

           AB=10

           AC=8

Solution :

Theorem :A transversal that is parallel to one of the sides in a triangle divides the other two sides proportionally.

So,

\frac{AD}{AB} =\frac{AE}{AC}

\frac{4}{10} =\frac{3.2}{8}

\frac{4}{10} =\frac{32}{80}

Reduce the fraction both sides by dividing both the fractions with common factor respectively.

\frac{2}{5} =\frac{2}{5}

Thus ans in boxes will be \frac{4}{10} =\frac{3.2}{8}

This verify that BC ∥ DE.

SOMEONE PLEASE HELP I CANT GET IT
AnnyKZ [126]
Answer:
y=3x+9

Explanation:
To answer this question, we first have to understand a few key concepts.

1) The equation given (y=3x+9) is written in slope-intercept form, which is y=mx+b.

Heres what the variables mean:
Y=the coordinate
M=the slope
X=the x coordinate
B=the y-intercept (the point on the line that intercepts the y-axis)

2) Parallel lines have the same slope. Using the given equation, we now know that the slope of line s is 3. Therefore, the slope of line t is also 3 (because they are parallel).

So now, this is our equation so far:
y=3x+b

All we need to do now is find b, which we can do by plugging in the coordinate (-6,-9) as the x and y variables.

y=3x+b
-9=3(-6)+b
-9=-18+b
Add 18 to both sides
-9+18=-18+b+18
9=b

And when we plug 9 into y=3x+b, we get:
y=3x+9

(And yes, they are pretty much the same line)

I hope this helps! Please comment if you have any questions.

1. Two angles are supplementary. Angle 1 measures
Serggg [28]

Answer:

34 degrees

Step-by-step explanation:

supplementary Angles are pair of angles whose sum is 180 degrees.

Given

Angle 1 = 4x + 6 degrees

Angle 2 = 38 degrees

Condition : angles are supplementary Angles

therefore

Angle 1 + Angle 2 =180

4x+6+38 = 180

=>4x+44 = 180

=> 4x = 180-44

=> 4x= 136

=>x = 34

Thus value of x is 34 degrees.

A 10-foot ramp must make an angle of 30degrees with the ground if it is to reach a certain window. What angle must a 15-foot ram
prohojiy [21]
<span>We know Sin theta is given by Perpendicular/ hypotenuse. Hence in this case the angle given is 30 degree and hypotenuse is given as 10 foot. Hence Sin 30= P/ 10 1/2= P/10 Hence on solving value of P is 5. Now we have to compute the theta value for Perpendicular as 5 and now the height of ramp is increased to 15 foot, hence hypotenuse is now 15 foot. Hence Sin theta= 5/15 On taking inverse of Sin Theta we will get the theta value as 19.47. Hence the angle of ramp should is 19.47 degrees.</span>
