Answer:

m=60º

n=30º

Step-by-step explanation:

a triangle is 180º total

an equilateral triangle has all 60º angles

since the one symbol for a right angle is cut between two triangles you can say that the one angle in the equilateral triangle +n=90º

substituting the values 60+n=90

so n=30

Then since a triangle is 180º you can make an equation that says 180=90+m+n

again substituting 180=90+m+30

60=m

an easy way to check is 180=90+30+60 180=180

Answer:

The result can be shown in multiple forms.

Exact Form:

2,5+D,4-1,3D

Decimal form;

2,5+D,3,3D

Step-by-step explanation:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.
