<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>
The answer is the first chart which would be A
Oh girl idek. What grade is this
Angle A should be equal to 47
I really don't understand what your saying but.....
1/3 = 0.3333333...... and 3/4 = 0.75 = 75%
Hope this helps:)
