The angle of NPR is 130°

First, set up an equation to find x.

$(3x-10)+2x+65=180$

Then, solve the equation for x.

$x=25$

Then, substitute 25 in for x in 2x

Finally, subtract 50 from 180 to find the angle of NPR

130°

Answer: 1. ∠A= 80.75° 2. 41.79 $cm^2$

Step-by-step explanation:

Since, According to the sines low,

$\frac{sin A}{CB} = \frac{sin C}{AB}$

Here, CB= 4.1 cm, AB = 3.3 and ∠ C = 52.6°

$\frac{sin A}{4.1} = \frac{sin 52.6}{3.3}$

⇒ $sin A = 4.1\times\frac{sin 52.6}{3.3}$

⇒ $sin A =0.98699998308$

⇒ A = 80.75°

2. Since, the area of the given figure = Area of the rectangle having dimension 8.3 × 4.2 + Area of the half square of radius 2.1

=34.86 + 6.93

= 41.79 square cm
