Aright triangle has an acute angle measure of 22°. which two numbers represent the lengths of the legs of this triangle? 1 and 5 2 and 5 3 and 5 4 and 5

Then the correct answer is B.) 2 and 5. (or your second option given above)

We will use the tangent ratio. 

tanΘ = opposite/adjacent

tan 22° = 2/5
0.404 = 0.40

Thus the two numbers that represent the lengths of the legs of the right triangle are 2 and 5.
