Omar wants to determine cos(-2) using the ratios of the 30° -60° -90° right triangle. How should he use this information to determine cos(- -)?

ye

step-by-step explanation:

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )
