Find the missing value to the nearest hundredth. cos_= 6/19

Olenka [21]

Let , missing value(_)=A

As, it is given that ,

$CosA=\frac{6}{19}\\\\ Cos A=0.3158\\\\ A=72 {\text{Degree}}$

To convert the value of A into Radians,

360°=2 π Radians

$1 {\text{degree}}=\frac{\pi}{180}\\\\72 {\text{Degree}} =\frac{72\times 22}{180 \times 7}\\\\=1.2571$

So, missing value to the nearest hundredth= 1.26 Radians

What set of Reflections and rotations could carry ABCD onto itself?

Nitella [24]

Reflect over y-axis,reflect over the X axis ,rotate 180°

Option D is the correct option.

Explanation:

Let's take point A which is (4,-1)

Reflection over y- axis will make this point (4,1)

Then, reflection over X axis will make this point (4,-1)

After rotation of 180 degree we will get (-4,1) .
