Answer:
<h2>x = 20</h2>
Step-by-step explanation:
To find x we use cosine
That's
cos ∅ = adjacent / hypotenuse
From the question
The adjacent is x
The hypotenuse is 28
So we have
cos 43 = x / 28
x = 28 cos 43
x = 20.477
x = 20 to the nearest tenth

Answer:
for the first one its a=8
for the second one the answer is their is no solution
for the last one the answer is p = -1.
Step-by-step explanation for the last one:
1)Expand.
30-6p=16-20p
2) Subtract 16 from both sides.
30-6p-16=-20p
3 Simplify 30-6p-16 to -6p+14.
-6p+14=-20p
4 Add 6p to both sides.
14=-20p+6p
5 Simplify -20p + 6p to −14p.
14=-14p14=−14p
6 Divide both sides by−14.
-1=p
7 Switch sides.
p=-1
Answer:
3x = 14
Step-by-step explanation:
Add the two equations.
5x + (-2x) = 3x
(-y) + y = 0
6 + 8 = 14
3x = 14.
