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

The point (2, -3 ) is reflected in the line x = 0 find the image

Mnenie [13.5K]

Answer:

The image of $P(x,y) = (2,-3)$ is $P'(x,y) = (-2, -3)$ .

Step-by-step explanation:

According to this statement, we need to find the image of a given point by reflection with respect to the y-axis. The reflection can be done by following operation:

$P(x,y) = (x, y) \to P'(x,y) = (-x, y)$ (1)

Where:

$P(x,y)$ - Original point.

$P'(x,y)$ - Reflected point.

If we know that $x = 2$ and $y = -3$ , then the reflecting point is:

$P'(x,y) = (-2, -3)$

The image of $P(x,y) = (2,-3)$ is $P'(x,y) = (-2, -3)$ .
