12. APPLICATION A 30°-60°-90 triangle and a 45-45°-90°
triangle are two drafting tools used by people In careers such as
engineering, archltecture, and drafting. The angles in both triangle
tools are combined to make a varlety of angle measures in hand-
drawn technical drawings, such as blueprints. Describe or illustrate a
procedure that will give the following angle measures.
а. 15°
b. 75°
c. 105°
13. Find the slope of the line that passes through each pair of polnts.
a. (4, 7) and (8, 7)
b. (2, 5) and (-6, 3)
14. Rudy is renting a cabin on Lake Tahoe. He wants to make a recipe for hot chocolate that calls
for 1 cup of milk. Unfortunately, he has only a 1-gallon container of milk, a 4-cup saucepan,
and an empty 12-ounce soda can. Describe or illustrate a process that Rudy can use to
measure exactly 1 cup of milk. (There are 8 ounces per cup and 16 cups per gallon.)
15. Draw a rectangle diagram to represent each product. Use the diagrams to expand cach
product.
b. (х + 3)2
c. (x+3)(x-3)
a. (x+ 1)(x + 5)
