Answer:
BC ≈ 8.9 units
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos36° =
=
=
( multiply both sides by 11 )
11 × cos36° = BC , then
BC ≈ 8.9 ( to the nearest tenth )
Answer:
step 3: he should have divided both sides by -7
Answer:
The last one
Step-by-step explanation:
in the second part, x2 could to pull out as x
Answer:
(-2,2)
Step-by-step explanation:
To solve the system, set the equations equal and solve for x.
x + 4 = -2x - 2
3x + 4 = -2
3x = -6
x = -2
Substitute x = -2 into one of the equations.
y = -2 + 4
y = 2
The solution is (-2,2).
