Yes, every equilateral triangle is acute because the angles are always congruent(identical) and 60 degrees which is acute. But I may be wrong. :P
Answer:
values of x and y is (4, -2), (0, 0) and (2, 10)
Step-by-step explanation:
2(x-5)=20
Divide both sides by 2 (division of property equality)
x - 5 = 10
Add 5 to both sides (addition of property equality)
x = 15
Answer
x = 15 is the solution
F^-1= positive or negative x square root
