This problem can be solved by making use of the Cosine Law. In general form, it is:
b2 = a2 + c2 - 2ac cos B

The given values are:
a = 8.75 cm
c = 4.26 cm
B = 87<span>°

Plugging in the values:
b2 = 8.75^2 + 4.26^2 - 2(8.75)(4.26) cos 87
b = 9.53 cm

So, the answer is:</span>

Which expression illustrates the associative property of addition?
4vir4ik [10]

Answer: THIRD OPTION.

Step-by-step explanation:

The Associative property of addition states that when three or more numbers are added, it does not matter how they are grouped, the sum is the same. Then:

a + (b + c) = (a + b) + c

Based on this and having the expression 3 + 19- 12, we can apply the Associative property as following:

(3 + 19) - 12 = 3 + (19 - 12)

Therefore, the  expression that illustrates the Associative property of addition is the one shown in the Third option.

Find the area of the rectangle with the given base and height.
Temka [501]

Answer: 3 1/3 ft^2

Step-by-step explanation:

Start by converting the inches into feet

1 ft = 12 in

4 in/1 x 1 ft/ 12 in = 4/12 ft = 1/3 ft

Now, imagine just multiply like normal for a rectangle:

Area of a rectangle = base x height

Area of rectangle = (10 ft) (1/3 ft)

Area of rectangle = 3 1/3 ft^2
