As you can see in the picture, this is 6-8-10 right triangle.
One of angles is 90° so you can find others
8/6 = 4/3
6/8= 3/4
tan-1(4/3) = 36.9 °
tan-1(3/4) = 53.1 °
tan<R= 53.1 °
Hope this helps ^-^

Answer:
<em>1.1n</em>
<em>0.6p</em>
<em>0.3b</em>
Step-by-step explanation:
<u>Simplifying Like terms</u>
Like or similar terms are those who have the same letters raised to the same power. For example, 5ab, -6ba, 0.6ab are like terms.
Terms like 5xy, -6xz, are not similar because they have different letters of powers.
The terms 1.6n-0.5n are similar and they can be simplified by operating their coefficients: 1.6-0.5=1.1. Thus
1.6n - 0.5n = 1.1n
Similarly, we can simplify 0.9p-0.3p. Operating 0.9-0.3=0.6 gives the result:
0.9p - 0.3p = 0.6p
Finally:
b - 0.7b = (1 - 0.7)b = 0.3b
Results:
1.1n
0.6p
0.3b
