<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>
Answer:
B) 190 cm^2
Step-by-step explanation:
Im pretty sure all you gotta do is
20x10 which is 200 then do 5x2
which is 10 and you minus 10 from 200
Please correct me if im wrong here
I dont really remember doing these
Answer:

Answer:
2/3 >=x
Step-by-step explanation:
8 =< -3x + 10
subtract 10 from each side
8-10 <= -3x+10-10
-2 <=-3x
divide by -3 (remember to flip the inequality)
-2/-3 >= -3x/-3
2/3 >=x
If it's adding to the 4,900 in the bank just add the numbers to 4,900.
