Once you know the height and width, multiply them to get the area of the square.<span> To </span>find<span> the perimeter of the square, add all four sides </span>together. <span>To </span>find the area of a triangle<span>, multiply </span>together<span> two of the sides not the hypotenuse and then multiply that figure by 1/2.</span>
Answer: Distributive hope this helps.
Step-by-step explanation:
Let's see what we can fill in here.
<ACE = 130
180 - 50 = 130
Now that we have two sides and an included angle, we can use the Law of Cosines.
Law of Cosines: c^2 = a^2 + b^2 - 2ab(cos(C))
Let's plug in what we know and solve!
c^2 = 40^2 + 38^2 - 2(40)(38)(cos(130))
R = 70.69706
Hope this helps!! :)
Answer:
b=-8
Step-by-step explanation:
9+1/4b=7
-2=1/4b
b=-8
You would mark 2 on the number line (open circle) and draw the rest of the line going < that way.
