Answer:
1,452,000
Step-by-step explanation:
Round up 844 to 1,000.
All angles on a triangle add up to 180. If it's a right triangle it would be set up like this: 90+3x-4=6x-5=180. You would subtract 90 from 180 and get 90 left. 3x-4+6x-5=90. Then you would add 5 and 4 to 90.....3x+6x=99. Then you add 3x and 6x then you would be left with 9x=99. Divide 99 by 9 and you get x=11.
Answer:
<h2>c. 16.5</h2>
Step-by-step explanation:
It's the right triangle.
The formula of an area of a right triangle:
Look at the picture.
We have
Substitute:
X-7 - -2x-5
answer is 2/3
X-7 + 2X= -2x-5+2x
3x-7= -5
3x-7+7= -5+7 (getting x alone)
3x=2
divide by 3 to get x
3x/3 =2/3
x=2/3
