A triangle with side lengths 3, 4, and 5 is a right triangle by the converse of the Pythagorean Theorem.
What are the measures of the acute angles?

36.87° and 53.13°

Step-by-step explanation:

the legs of the right triangle are 3 and 4 and the hypotenuse is 5

tan x = 3/4

x = arctan (3/4)

  = 36.87° =  measure on one acute angle

90 - 36.87 = 53.13° = measure of the other acute angle

This is what I got for this question but if I did it wrong I'm sorry

Step-by-step explanation:

Formula- c^2 < a^2 + b^2

3^2 + 4^2 5^2

9+16= 25 25

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

is there any photos or whatever?
