Answer:
Option d.
Step-by-step explanation:
For this problem we have 2 sides of a triangle (a and b) and the angle between them C = 160 °.
We have a triangle of type SAS.
We have:
a=25
b=30
C= 160°
Then we use the law of cosine.
Now we substitute the values in the formula to find c
Now we use the cosine theorem to find B. (You can also use the sine)
Finally:
Answer:
x= 2
y = 20
Step-by-step explanation:
y = 6x + 8
y = –4x – 2
y = 4 (6x + 8
)
y = 6 (–4x – 2)
y = 24x + 32
y = –24 -12
___________
y = 20
input that back into the equation to find x
20 = 6x + 8
20 - 8 = 6x
12 = 6x
x= 2
Is it 8 oranges? What do you think?
You can add - 1/3. Hope it helps! If you could vote my answer as the brainiest, that would be awesome! :)
