The answer is A which is 18 square inches. This is because the formula for finding the area of a triangle is 1/2 multiplied by the length of the base multiplied by the height. And so when you calculate this, you will get 18 square inches :)
Answer:
If you really meant that the number of dogs is 12 greater than 3 times the number of cats then:
3 cats
Step-by-step explanation:
21= number of dogs
c = number of cats
21 = 12 + (3c)
3c = 9
c = 3
The answer is A SSS because
The first diagram below shows a circle with a radius of 1 (unit circle). The circle is drawn on a Cartesian graph with (0,0) as the center of the circle.
From the second diagram, we can determine the value of sin(Θ) = y
and cos(Θ) = x
We can further deduce that
tan(Θ) =

sec(Θ) =

=

cosec(Θ) =

=

cot(Θ) =

=
