How do you find the area of a triangle when given only the lengths of three sides?
SashulF [63]

Answer:

Use Heron's formula; see below.

Step-by-step explanation:

Use Heron's formula.

Let the sides of the triangle have lengths a, b, and c.

s = \dfrac{a + b + c}{2}

area = \sqrt{s(s - a)(s - b)(s - c)}

Example:

A triangle has side lengths 3, 4, and 5 units.

Find the area of the triangle.

s = \dfrac{a + b + c}{2}

s = \dfrac{3 + 4 + 5}{2}

s = 6

area = \sqrt{s(s - a)(s - b)(s - c)}

area = \sqrt{6(6 - 3)(6 - 4)(6 - 5)}

area = \sqrt{6(3)(2)(1)}

area = \sqrt{36}

area = 6

Please help I do not get
katen-ka-za [31]

Answer:

(a) 51%

(b) 41%

Step-by-step explanation:

We can simplify this problem down by realizing that the amount of girls over 200 will get us our percentage as a decimal.

Looking at this table, we can see that 30+72=102 girls were asked. So, 102\div200=0.51, and 0.51\cdot100=51.

We can also see that 30+52=82 people preferred video games, so 82\div200=0.41, and 0.41\cdot100=41.

Hope this helped!
