Hello
let Brenda drive B miles and Jan drive J miles.
<span>by first sentence : </span><span>B=3J</span>
<span>by 2nd sentence : </span><span>B=J+24</span>
<span>so </span>
<span>3J=J+24</span>
<span>2J=24</span>
<span>J=12</span><span> miles
</span>
Have a nice day
Let the first angle be x
Sum of complementary angle is 90
Then second angle will be 90- x
As difference is 14
Therefore
x - (90-x) =14
x-90+x=14
2x = 14 +90
x = 104/2
x = 52
In goes 4.
We then subtract 7.
So, 4 - 7 = -3
We now divide -3 by 3.
The output is -1.
So the perimeter of the first triangle is 30; since you are given each side you can set up 3 ratios to find the unknown side lengths.
Thus side 5 would correspond to 2.5
Side 12 would correspond to 6
And side 13 would be 6.5
Another way to look at it is that since the perimeter of triangle 2 decreases by half (from 30 to 15), you can assume all side will also decrease by half
