Answer:
A. Right angle -- if you multiply the slopes of 2 intersecting lines and you "-1" then the lines are perpendicular - in this case the line in quadrant 3 has a slope of "1" and the line in quadrant 4 has a slope of "-1", hence their product is "-1" and the angles formed at the intersection of the lines are right angles.
Step-by-step explanation:
Given:
uniforms in a package of 8.
127 people with 3 uniforms each.
127 x 3 = 381 uniforms
381 ÷ 8 = 47.625 ⇒ 48 packages
The store will need to order 48 packages of uniforms to fulfill the uniform requirement of 127 people. There will also be 3 uniforms left in excess of the 48 packages.
48 * 8 = 384
384 - 381 = 3 excess uniform
The angles inside a triangle always add up to 180 degrees.
The whole thing is one big triangle made of two smaller ones.
28 + 58 + 77 + x = 180
163 + x = 180
x = 180 - 163
x = 17
Answer is B, -6 - -6 = 0 7-3=4 0/4 =0
A’s slope has no meaning
C’s slope is 1
D’s slope is -14/-18
