Acute angle and a right angle makes a obtuse I learned this in 4th
Answer:
d.) simplify the expression inside the pipe symbols
Answer: C
Step-by-step explanation:
On the left side, there are 2 triangles and 6 2's, so this equals 2x+12.
On the right side, there are 4 triangles and 2 2's, so this equals 4x+4.
Meaning 2x+12=4x+4.
12=2x+4
2x=8.
You would do 40/x=x/15, therefore you get x^2=600. to find x you find the square root of each side. Rounded to the nearest tenth, you get 24.5. If you put it in simplest radical form you should get 10 times the square root of 6
