Question

I'm confused on this​

Answer 1

Answer:

AB = 33.78228208

BD = 42.3

AT= 20.33068487

Area= 859.9879701

Step-by-step explanation:

Using the sin rule:

sinA = sinB

a b

If I use A = 90, a= 42.3

B = 53, b= AB

I get AB = 33.78228208 units

Then the diagonal is already 42.3 cm so I think. BD should be 42.3 cm too.

I used the sin rule again for ABD to find AD but by using B as 37° and b as AD.

I get AD = 25.45677548

For ADT,

AD is the hypotenuse.

Now I get from the same sin rule,

A= 90°. a= 25.45677548

B= 53°. b = AT

AT= 20.33068487 units.

Area of rectangle = l×b

= AB × AD

so that gives me 859.9879701 square units
