Answer:
i believe it is c
Step-by-step explanation:
None because it is impossible for any triangle to have more than one obtuse angle.
Answer:
The correct answer is D. AB ≅ WX
Step-by-step explanation:
No other choice involves a pair of congruent/similar lines. If the figure is rotated clockwise, you could transpose one over the other and AB would overlay WX exactly.
Answer:
(-2.2, -1.6), (3, 1)
Step-by-step explanation:
You don't have to go far to find the equations. They are right there in your problem statement. Perhaps you want to find the solutions to the equations.
Use the first equation to write an expression for x, then substitute that into the second equation:
x = 2y +1
y^2 -3(2y+1)(y) +8 = 0
-5y^2 -3y +8 = 0
-(5y +8)(y -1) = 0
y = -8/5 or y = 1
The corresponding values of x are ...
x = 2(-8/5)+1 = -11/5
x = 2(1) +1 = 3
The solutions are (x, y) = (-2.2, -1.6) and (3, 1).
