Answer:
1/10
Step-by-step explanation:
1/2 - 2/5
common denominator is 10 (2x5)
5/10 - 4/10 = 1/10
It’s kinda hard to read but 3/10 is first on .3, 4/5 is next on .4, and then pi/5 is last on .6
The measure of the angle R is 
Explanation:
It is given that the lengths of the triangle are PQ = 8 and QR = 3
To find the angle of R using the opposite and adjacent side, we shall use the tangent formula.

where opp = 8 and adj = 3
Thus, substituting these values in the formula, we get,

Multiplying both sides by
, we get,

Dividing, we get,

Rounding off to the nearest tenth, we have,

Thus, the measure of the angle R is
