<u><em>Answer: the answer is 10! B)X=10 </em></u>
Answer:
x=-2 , y=9
Step-by-step explanation:
A larger sample will give more reliable information
0 < a < 180/2, is just another way of saying 0° < a < 90°, which is another way of saying angle "a" is in the I Quadrant, where cosine and sine or x,y are both positive.
Answer:
x = 18
Step-by-step explanation:
By the rule of Consecutive Interior Angles which define what these angles are, they both will add up to 180. As such we can put the sum of these two angles set equal to 180, and solve algebraically
(8x - 20) + (3x + 2) = 180
8x - 20 + 3x + 2 = 180
11x - 18 = 180
<u> + 18 +18</u>
11x = 198
x = 198/11
x = 18
