Question

What is the area of this triangle?

Answer 1

So to get the answer you: 

11*9 
 ------    X    Sin63 =    44.104 or 44.1 
    2
Or 11 times 9 divided by 2 times Sin63 equals 44.104 and because it says round to the nearest tenth 44.1 
Hope it helps.

Answer 2

Answer:

Area of the triangle = 44.1 cm²

Step-by-step explanation:

In the given triangle

area of the triangle = (1/2) × Base × height

and sin 63° = Height/ Hypotenuse = Height/11

0.891 = Height/11

Height = 11×0.891 = 9.80

Therefore Area of the triangle = (1/2)×9.80×9 = 44.1 cm²

answer is area = 44.1 cm²
