how many cross sections can a rectangular pyramid have?
3. a rectangle, triangle, and trapezoid. open page 248 in your books to seee
what are suplementary and complementary angles?
complementary: two angles whose sum are 90 degrees
suplementary: two angles whose sum is 180 degrees
true or false: ussually, in suplementary angles, one angle is acute and the other is obtuse
true
name one possible cross section of a sphere
circle
lets suppose you now that angles n and l are suplementary. the measurment of angle n is 21 times more than the amount of lessons there is in chapter 8. what is the measure of angle l?
4 lessons times 21 is 84. 180 minus 84 is 96. angle l is 96 degrees
