Answer:
a. 90º
Explanation:
The chords ST and RA intesect at Y, so that SY is now perpendicular to RY and they form an angle 90 degrees at that point. However angles mSA and mRT are both at the circumference of the circle(a chord is a line from point of a circle's circumference to the other) and are both 90 degrees because angle at the circumference is half of angle at the centre in same arc.
By definition we have to:
Monomy: Algebraic expression that consists of a single term or in which the terms that form it are related by the product operation.
For example:
ax^2
It is a monomial.
In this case we have the following expression:
18x
Using the given definition, we have that the expression is a monomial.
Answer:
A .. monomial
Answer:
answer is 12
Step-by-step explanation:
if you take 15 and subtract it by 7 that would give you the number of neon tetra fish, then you can add 4 to give you your total number which is 12 :)
