Answer: Choice A) Obtuse
The angle 126 degrees is larger than 90 degrees. Any time you have a triangle with one angle larger than 90 degrees, you'll always have an obtuse triangle. This is by definition of what "obtuse triangle" means.
3x-7+c=x^2+4x-1
find c
minus 3x from both sides
-7+c=x^2+x-1
add 7 to both sides
c=x^2+x+6
x^2+x+6 must be added
Answer:
28, 29, 31, 32
Step-by-step explanation:
the number of workers he normally has + the number of extra workers he hires for harvesting = total number of employees
so 26+b=c
Answer:
112
Step-by-step explanation:
1 bag- Has 14 marbles in all
So if you multiply 14 times 8 total bags you get 112.
For the main question, it's basically just the Pythagorean's Theorem, 400-144= 256, square root of 256 is 16, so it reaches 16 feet up the building.
For Picture 1: Another Pythagorean's Theorem question, since the two angles are both 45 degrees, then LM and KM are the same. They are both 5, so they both square to 25, added together 50. So we do square root of 50, and then you can change it to square root of 25 * square root of 2. And then you can change it to 5 * square root of 2.
Picture 2: isn't it the exact same?
