Step-by-step explanation:
180°= 3q+q+q (Sum of angles in a triangle)
180°=5q
q=180÷5
q=36
Acute angle=36°
Obtuse angle=108°
X+2> _ 5, x >_5-2, x>_3
-x-2>_5, x<_ -2-5, x<_-7
the last is the answer
Answer:
D.
Explanation:
PEMDAS method. First do the parentheses. Multiply first, then subtract 12 from that number. Once finished with the parentheses, multiply by 8.

4*3
Answer:
A8 = 66 [8th term]
Step-by-step explanation:
Given the explicit arithmetic sequence An = -14 + 10n → -4 + 10(n-1)
To find the 8th term. An nth term is where n is n in the sequence. So substitute 8 for n, and simplify.
So A8 = -4 + 10(8-1) → -4 + 10(7) → -4 + 70 → 70 - 4 → 66.
