Jake drew an isolsceles triange.
10a. What are the measures of the two acute angles?
10b. How do you know?


Well, first I need to explain A for you to understand B. 
So, an isosceles triangle has two equal angles. Assuming that the third angle is obtuse, it has to be greater than 90 degrees. 
Now, do 180-91. that equals 89. 89 divided by two equals 44.5. This is an acute angle, and 44.5+44.5+89=180. 180 is the sum of the angles of a triangle

For B, it's honestly just a description of the way you did it. You can use what I did or if you did a different method. 
Sorry it's so late! I hope it's on time!

Ty is painting a rectangle that is 10 inches long and 7 inches high. What attributes of a rectangle can you share with Ty to help him paint his rectangle?


The area of the rectangle Ty is painting is 70 inches squared

Final answer:

A rectangle is a quadrilateral with four 90-degree angles. The opposite sides are equal, with two sides being the length (10 inches) and the other two being the width (7 inches).


Ty, when painting a rectangle, it's important to understand its attributes. A rectangle is a quadrilateral, meaning it has four sides. Two of these sides will be 10 inches long, and the other two will be 7 inches high - these are referred to as the 'length' and 'width'. Additionally, all interior angles of a rectangle are 90 degrees, which is a right angle. So when you are painting, make sure each corner forms a 90-degree angle. Also, the opposite sides of a rectangle are always equal. If any of these attributes are not followed, the figure will not be a rectangle.
