Answer:
90°
Step-by-step explanation:
Angles in a triangle add up to 180°
The two angles you have add up to 90°
You need another 90° to make it 180°
Answer:
The answer to your question is below
Step-by-step explanation:
Sadie should have left inside the root an exponent lower than the root and the power of "a" is higher than "2", the root is squared.
Right solution
54 = 3² 6
a⁷ = a⁶ a
b³ = b² b
=
=
=
X=8+y
x+y=70
Rewrite the first equation to x-y=8
Copy the second equation x+y=70
Add the two equations and you get 2x=78
Therefore, x=39. Since this is the bigger number the smaller number(y) would have to be 31 because you subtract 8 from x which is 39. 39 is your answer.
Answer: So, the length (L) = 7 3/4 ft = 31/4 (as an improper fraction)
the width (W) = (1/3)xL
So the width = 1/3 x (31/4) =
31/12 = 2 7/12 feet
Step-by-step explanation:
whenever you get an equality like so, that's a flat that both equations are exactly one and the same and thus the system has "infinitely many solutions".
