How to convert 2 years 4 months to years

2 1/3 years

Step-by-step explanation:

4 months = 1/3 years

2 + 1/3 = 2 1/3 years

2.25 years

Step-by-step explanation:

(D) LA

Step-by-step explanation:

Given: ∠C and ∠F are right angles and ∠B=∠E; BC=EF

To find:  the abbreviation of the postulate or theorem that supports the conclusion that the triangles are congruent.

Solution:

From the given triangles, ΔABC and ΔDEF,

∠C=∠F=90°(given)

∠B = ∠E(given)

BC = EF (given)

therefore, BC and EF are corresponding legs of these triangles. Also, ∠B = ∠E.

Thus, we have congruent corresponding legs, that are included between right angle and given angle, and corresponding congruent angles, so

we need to use LA (leg-angle) theorem.

Hence, option D is correct.
