14. B (4, -2)
15. I am not exactly sure about this one but I would say either A or B.
Answer:
10
Step-by-step explanation:
<h3>Calculating BC</h3><h3>BC = √2^2 + 11^2 </h3><h3>BC = √ 4+121</h3><h3>BC = √ 125 = 11.18</h3>
to find measure of angle C use sinerule
<h3>sinC/C = sinA/A</h3><h3>sinC/2= Sin90/11.18</h3><h3>SinC = 2×1/11.18</h3>
<h3>sinC = 2/11.18</h3><h3>sinC = (0.1788)</h3><h3>C = sin^-1(0.1788)</h3>
<h3>C = 10.305</h3><h3>C = 10 (approximately)</h3>
9/18 in lowest term is 1/2
Work:
9/18 ÷ 9/9 = 1/2
1/2 = 0.5
0.5 = 50%
Answer:
The answer is 3
Step-by-step explanation:
4 x 3 = 12
8 + 12 = 20
