Use the triangle angle theorem:
All interior angles of a triangle equal 180 degrees.
If you use the theorem you should get the first one 19,70,91
If the areas of two equilateral triangles are 27 yd² and 75 yd², then the ratio of these areas is 27/75 = 9/25
If the ratios of the areas are 9:25, then their similarity ratio and the ratio of their perimeters is √9:√35 = 3:5.
3 : 5; 3 : 5 <==ANSWER
Y=- \frac{7}{3}

.
To find the equation of a line, you need two things: the slope and the y-intercept.
The slopes of parallel lines are the same. So we can find the slope of the new line by finding the slope of the first line. To do that, we need to put it in y=mx+b format, where m is the slope. So we must rearrange the 7x+3y=10. First subtract 7x from both sides to make it look like:

Then divide both sides three:
b

So now that it's in y=mx+b format, we can now see that the m= - \frac{7}{3}
Now we know the m of the new equation, we need to find the b, or the y-intercept. To do this, we can plug the point we have and the m value into the y=mx+b format.

Solving this, we can subtract 7/3 from both sides:

Therefore, b=

Plugging the m= - \frac{7}{3} and the b=

back into the y=mx+b format, your parallel line is y=- \frac{7}{3}

Answer:
72 cubic meters
Step-by-step explanation:
Again to calculate volume you have to take all three measurements given and multiply them like so: x times y times z. In this case x = 4, y = 1 and z = 18. When you multiply all of these terms you get 72 cubic meters.
