Answer:
6=n
Step-by-step explanation:
Hi there!
We are given this equation:
3(n+4)=5n
And we need to solve it for n
To do that, we need to isolate n on one side
But we need to open up the parentheses on the left side by doing the distributive property
Multiply both n and 4 by 3
3n+12=5n
Now subtract 3n from both sides to remove it from the left side
12=2n
Divide both sides by 2 to change the coefficient on n from 2 to 1
<u>6=n</u>
n is now isolated on one side
Hope this helps!

Answer: 42°
Step-by-step explanation:
Complimentary angles are angles sum up to make 90°
From the ratio given 7:8,
Add the ratios together and find the smaller angle as follows
7 + 8 = 15
Therefore,
⁷/₁₅ x 90 = 42°
The smaller angle is 42°
