You have to divide 128 by 8 and you will get 16. So the answer is 16
Answer:

Step-by-step explanation:
The acute angles of a right-angled triangle other than the right angle always add up to 90 degrees.
<u>So, we get:</u>
(48 - x) + (3x - 10) = 90
48 - x + 3x - 10 = 90
-x + 3x - 10 + 48 = 90
2x + 38 = 90
2x = 90 - 38
2x = 52
Divide both sides by 2
x = 52 / 2
x = 26

Sin 28 = 3/AB
AB= 3/ sin 28
AB=6.4
Answer:
a) 6r + 3
b) 8 + 4d
c) -2mn
d) 6s - 10
Step-by-step explanation:
a) 2r + 3 + 4r
We need to add the like terms
= 2r + 4r + 3
= 6r + 3
b) 8 + 3d + d
We need to add the like terms
= 8 + 3d + d
= 8+4d
c) mn + (–3mn)
We need to add the like terms
= mn - 3mn
= -2mn
d) 10s + (–10) + (–4s)
We need to add the like terms
= 10s –10 –4s
= 10s - 4s - 10
= 6s - 10
