Answer:
The answer is the option B, which is: 46 degrees.
The explanation for this problem is shown below:
1. According to the Law of reflection, the angle of incidence is equal to the angle of reflection.
2. Therefore, if Ф1 is the angle of incidence and Ф2 is the angle of reflection, you have:
Ф1 = 46 degrees
Ф1 = Ф2
Ф2 = 46 degrees
So, the answer is the option mentioned before.
Answer:
-100
Step-by-step explanation:
18(2a-b)-4(2a-b)-13
=36a-18b-8a+4b-13
Rearrange
=36a-8a-18b+4b-13
=28a-14b-13
Answer:
4459/36
Step-by-step explanation:
This is the concept of algebra, we are required to approximate the arcsin of the value given using a calculator;
sin theta=[opposite]/[hypotenuse]
arcsin is the inverse of sin, thus;
arcsin(0.549)=33.2984
the answer is 33.3984°
