Answer:
-1/3
Step-by-step explanation:
Take the ratio of the corresponding sides to get the scale factor so for this equation let's use the hypotenuse.
The length of the hypotenuse of the larger triangle is 12 units and the smaller triangle's hypotenuse is 4 so 4/12 is the scale factor.
However 4/12 can be simplified down to 1/3.
Since the smaller triangle has been flipped upside down the scale factor is negative so the final answer is -1/3
First angle= x+10
Second angle = x
Third angle = x+x+10 or 2x+10
X+10+x+2x +10=180
4x+20=180
Subtract 20 from both sides
4x=160
Divide both sides by 4
X=40
First angle =50
Second angle=40
Third angle =90
Answer:
the answer is 5.1%
Step-by-step explanation:
first you divide 37 by 39 to get .94871795
next you would subtract 1 by that number and you get
.05128205 which can be rounded to .051 or 5.1%

<h3>
Step-by-step explanation:</h3>
We know that
, so substitute that into the equation. 
With negative powers, instead of making the result negative, you divide one by it. Mathematically speaking,
. This makes our equation: 
Finally, simplify the exponent.
