(x - 4)²
(x - 4)(x - 4)
x² - 4x - 4x + 16
x² - 8x +16
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>
