Answer:

<em>x=8</em>

Step-by-step explanation:

<u>Triangles</u>

An isosceles triangle is a triangle with two equal sides. The angles the equal sides form with the third side are also equal.

The triangle shown in the figure is isosceles and the angles marked as '2' and 67° are equal. But we are also given that the angle '2' equals 8x+3, thus:

8x+3=67

Reducing:

8x=67-3=64

Solving:

x=64/8

x=8

The image shows a ray of light bending at the boundary of a glass block. According to a law of optics, = n, where n is a constan
UkoKoshka [18]
The formula for the light bend would be n1*sin i= n2 * sin r

If you use "sin (90-x)= cos x" principle, you can change the sin in the equation into
n1*sin i= n2 * sin r
n1 * cos a= n2 * cos b
n2/n1= cos a/ cos b

Assuming the n constant is the ratio of the glass compared to water then the answer would be: cos a/ cos b
