The answer is 3, because the other two sides are 3 and the angle is 60, so the other angles will have to be 60. That means it is an equilateral triangle.

The area of the triangle below is 10.6 square centimeters. What is the length of the

CaHeK987 [17]

Answer:

6 cm

Step-by-step explanation:

The area of a triangle is $\frac{bh}{2} = A$ , where b = base, h = height, and A = area. In this case, we're given the height as 4 cm and the area as 6 cm^2.

Let's plug in these values.

$\frac{4b}{2} = 6$

Now, let's solve this algebraically.

Step 1: Multiply both sides by 2.

$\frac{4b}{2} * 2 = 6 * 2$
$4b = 12$

Step 2: Divide both sides by 4.

$\frac{4b}{4} = \frac{12}{4}$
$b = 3$

Step 3: Check if solution is correct.

$\frac{3*4}{2} = 6$
$\frac{12}{2} = 6$
$6 = 6$

Therefore, the base is 6 cm. (but don't put the cm in the box because it's already there)

Have a lovely rest of your day/night, and good luck with your assignments! ♡
