Answer:
Step-by-step explanation:
The angle of incidence and reflection is 45°
The angle between them is 90°
they lie on the same plane, and angle of incidence = angle of reflection
the sum of all the angles is 180°
let angle of incidence and reflection be x
therefore,
90 + 2x = 180
x = 45°
Answer:
-1 is the first answer of question
-8 is the answer of second question
Hi!
So, we have a value which is 23. We want to algebraically write this to say that this value we have is <em>less than </em>this variable we have.
In order to do this, we're going to use the algebraic symbol for <em>'less than', </em>which is <.
If you look closely, you can see that the smallest part of the symbol is pointing to the number which is <em>less than </em>another number!
We also have other possibilities such as saying <em>greater than, </em>which we would use the > symbol for.
Another variation is saying <em>less than or equal to, </em>or <em>greater than or equal to. </em>To do this, we just add an equal sign at the end! (<=, >=).
Now time to answer the question -
To write in algebraically, we would put 23 < x.
Hopefully, this helps! =)
