c
Step-by-step explanation:
Consider the ratio of image to original, that is
scale factor = = = 4 → C
Do you mean 0.8 = 8/10 = 80%? Ohhh... then it's 1.25!
Hope this helps!
Answer:
The measure of the third angle = 103°
Step-by-step explanation:
The sum of all the angles in any triangle is 180°. Given the two angles of 50° and 27°, we can set up an equation to find the measure of the third angle:
Equation: 50 + 27 + x = 180
Combine like terms: 77 + x = 180
Inverse operations: 77 + x - 77 = 180 - 77
Solve: x = 103°
Answer:
Step-by-step explanation:
Angle of incidence is the angle formed at the point of incidence between the incident ray and the normal. Angle of refraction is the angle formed between the refracted ray and the normal .
According to Snell's law,
Here, are indexes of incidence and refraction.
are angles of incidence and refraction.
Given:
On putting these values in the Snell's law, we get
11.99 x 0.1 = 1.20
11.99 - 1.20 = 10.79
10.79 x 0.07 = 0.76
10.79 + 0.76 = 11.55
Your final answer is $11.55
