Jus look and the answer above
I have no idea what your talking about haha could you be a little more specific?
Answer:
CE = 100°
Step-by-step explanation:
Using the cofunction identity
sin x = cos(90 - x)
Given x = 20°, then 90° - 20° = 70° thus
CE - 30 = 70° ( add 30 to both sides )
CE = 100°
Thus
sin20° = cos(100 - 30)° = cos70°
Answer:
Step-by-step explanation:
I'm not certain I understand your question.
Let's start at the beginning. What you are supposed to do is find the area of the 4 triangles.
QRP is one of the tringles. It has a height of RS which is 6 cm. The base of the triangle comes from the square on the bottom of the diagram (and yes it is an optical illusion).
The square has a side length of 8 cm.
Area QRP = 1/2 * base * height
base = 8 cm
height = 6 cm
Area QRP = 1/2 * 8 *6 = 24 Oh that's where you got 24 * 4
There are 4 triangles that are the same as QRP so the answer is 24*4
The base of the triangle is included. It is just a bit disguised. It comes from the 24. Excellent question.
Well, im going to say that the range is also all real numbers, since there is no limit of the domain.
because if u plug in any number into the equation, u can get any answer.
