How do you find the area of a triangle
natita [175]
Use the formula:

\frac{b\: \times \:h}{2}

B refers to the base and H refers to the height of the triangle.

As such, multiply both the base and height of the triangle and divide the answer by 2, to find the area of the triangle.

Help pls i need this luv you guys ,&lt;333
bagirrra123 [75]

Answer:

x ≈ 3.1 ft

Step-by-step explanation:

The segment from the centre to the chord is a perpendicular bisector, thus

The triangle is right with base = \frac{1}{2} x

Applying Pythagoras' identity to the right triangle, then

(\frac{1}{2} x )² + 1.4² = 2.1²

\frac{1}{4} x² + 1.96 = 4.41 ( subtract 1.96 from both sides )

\frac{1}{4} x² = 2.45 ( multiply both sides by 4 )

x² = 9.8 ( take the square root of both sides )

x = \sqrt{9.8} ≈ 3.1 ft ( to the nearest tenth )
