You would use the Law of Sines here. First realize that if A and B equal 35 and 65 respectively, C=180-65-35=80°. Then from the Law of Sines:
b/sin65=15/sin80
b=15sin65/sin80
b≈13.8 units (to the nearest tenth of a unit)
Answer:
direct variation has no constant and x is on top
EX:
y=5x/4 or y=4x or y/3=x
The triangles ABC and CED are similar
⇒AB/EC=BC/DE=AC/CD
The reason is the last one:
Corresponding side lengths in similar triangles are proportional in lengh.
It should be noted that a relation that's both symmetric and antisymmetric is R = {a, b) | a= b}.
<h3>What is a relation?</h3>
A relation in mathematics simply means the relationship between two or more variables.
In this case, the relation that's both symmetric and antisymmetric is R = {a, b) | a= b}.
On the other hand, a relation on a set that is neither symmetric nor antisymmetric will be R = {a, b) | a < = b}
This is not symmetric because a < b and v < a can never be butt true.
