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

Type only a number for your answer​
UNO [17]

Answer:

x = 80

Step-by-step explanation:

x + 30 = 110 (opposite sides are congruent/equal)

x = 110 - 30 (subtract the 30 from both sides to get X by itself)

x = 80 (simplify)

Margie says the set of numbers, 0.1, -1, -2 1/4, 3, are in order from least to greatest. What is her error?
ANEK [815]

Her error was that she thought 0.1 and 1/4 were negatives but they are still positive.

She also thought the larger the negative the greatest one. The smaller negative is the greatest because it's bellow 0.

To solve this you would first need to turn 1/4 into 0.25

It would start out with -2 cause that is the least. Then -1. Now its back to positive so the least to greatest would be normal.

So the real answer would be -2, -1, 0.1, 1/4
