Answer:
So the height is 12
Step-by-step explanation:
Let W be the width
Let W- 4 be the height
W2 +(W-4)2 = 400
So: W2 -4W-192 =0
One uses the quadratic solution:
W = (4 + (16 + 4*192).5)/2 = 16
3/5-1/3=9/15-5/15=4/15
4/15x=10
10÷4/15=10×15/4=150/4=37 1/2
On any right triangle that has 45 degree angles the hypotenuse is the length of the side x sqrt(2)
the answer would be 8 sqrt2
Well, if you're rounding to 1 significant figure, which you'll mostly be asked to do,
You look and see which number is the first one which isn't a zero. The most significant. In this example, the 8. You then need to look at the second number, it's a zero. It has no value and doesn't do anything to the 8. The number after that gets rounded down to a zero, it's too far away to effect the 8, and even if it could it's too low.
The answer is 8.
(Sorry if my answer was a bit complicated...)
The answer is c, 32. QS and TV are congruent. You set them equal to each other. And find v, v is 6 and find QS, which is 32. Since they are congruent, both QS and TV are 32
