Answer:
the answer is a. scales triangle
Step-by-step explanation:
21^2 + 12^2= 28^2
441 + 144<784
<em>Since we are given with the three sides of the triangle and asked to determine the angle, we can use the cosine law.</em>
<em> b² = a² + c² - 2ac(cosB)</em>
<em>Substituting the known values,</em>
<em> (1.8)² = (2.4)² + (1.6)² - 2(2.4)(1.6)(cosB)</em>
<em>The value of B from the equation is 48.6°. </em>
Hello from MrBillDoesMath!
