Is the expression shown below rational? (6 +v16)/5) + V7
Yes, because the sum of two irrational numbers is rational
No, because the sum of two irrational numbers is irrational
Yes, because the sum of a rational number and an irrational number is rational
No, because the sum of a rational number and an irrational number is irrational

x

step-by-step explanation:

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
