What is the area of this triangle?

Mathematics

Naddika [18.5K]3 years ago
5 0

Answer:

Area of the given triangle = 6.51 ft²

Step-by-step explanation:

If we redraw the triangle as shown in the figure attached we get the height of the triangle as x feet and base = 4.3 feet

Therefore area of ΔABC = (1/2) × Height (AD) × Base(BC)

From ΔABD

sin 53 = AD/AB = x/3.8

x = 3.8 × sin 53

= 3.8 × 0.7986 = 3.03 feet

Now area of ΔABC = (1/2)×3.03×4.3 = 6.51 feet²

The order operations, PEDMAS, must be applied:

We have Addition and Division here,

Using PEDMAS, we must divide first to get:

step \: 5 : 2 + 5

We can now add to get:

step \: 6: 7
