Can somebody help me with writing a real-life problem on this subject Finding angle measures of a right or isosceles triangle given angles with variables thank you?

See Explanation

Step-by-step explanation:

See attachment for illustration

(a) Right triangle

The sum of in a is:

Subtract 90 from bot sides

Make x the subject

Make y the subject

This implies that, subtract the known angle from 90 to get the unknown angle.

Assume

We make use of:

(b) Isosceles triangle

The sum of angles in an isosceles triangle is:

---- y appear twice because the base angles are equal

Make x the subject

Make y the subject

Assume , we make use of:

Assume , we make use of:

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".
