For the triangles to be congruent
x=y+5 .......(substitute in the second equation)
x+3=3y.........(y+5) + 3 = 3y , 2y = 8 ,
y = 4 , x = 9
Answer:
-5, -1, 0, |-1|, |-3|
Step-by-step explanation:
|-3| = 3
|-1| = 1
-5, -1, 0, 1, 3
Note that abosulate value changes the number to being positive at all times.
Best of Luck!
3x and -2x are like terms because they both have the variable X
Answer:
3a^2
Step-by-step explanation:
2a-2a is equivalent to 0 there by making 3a^2 remaining
Answer:
Step-by-step explanation:
arccos(0) = 90 degrees
Cos is 0 when ever sin(x) =-1 this occurs at 270 degrees and when sin(x) = 1 at 90 degrees. However, the domain of arccos(x) is restricted from 0 to pi. So the value of arccos(0) is pi/2 or 90 degrees.
