Choose the congruence theorem that you would use to prove the triangles congruent

Step-by-step explanation:

In the first picture , we have two triangles where two sides and one include angle of first triangle is congruent to the corresponding two sides and one include angle.

Then by SAS-postulate of congruence, the both triangles are congruent.

In the second picture, we have two right triangle where hypotenuse and one leg of first triangle is congruent to the corresponding hypotenuse and one leg.

Then by HL theorem of congruence, the both triangles are congruent.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
