Answer: 131.1287 square mm (approx)
Step-by-step explanation:
The area of a triangle,
Where and are adjacent sides and is the include angle of these sides,
Here PR and QR are adjacent sides and ∠R is the included angle of these sides,
Thus, we can write,
, and ,
Thus, the area of the triangle PQR,
Answer:
(14-9i)+(2+3i) = 16-6i
Step-by-step explanation:
We need to find the equivalent of (14-9i)+(2+3i).
We need to add the two expressions.
(14-9i)+(2+3i) = 14+2 -9i+3i
= 16-6i
Here, the real part is 16
The imaginary part is -6
Hence, the required answer is equal to 16-6i.
It would be B. 28 square yards
Answer:
A
Step-by-step explanation:
Answer:
The area of the triangle should be: [(1 + 5 + 4) × 11]/2= 55 (ft²)
The area of the rectangle should be: 5 × 2 = 10 (ft²)
The area of the shaded region is: 55 - 10 = 45 (ft²)
