Answer:
x= 30
Step-by-step explanation:
angle AOB= 180- 4x
angle AOC is a right angle because OA is perpendicular to OC
180- 4x + x = 90 degrees
180- 3x = 90 degree
180- 90 = 3x
90= 3x
therefore x= 90/3= 30

Answer: y = -1/2
Discussion:
As x approaches plus or minus infinity the function behaves like
(-3x^5)/ (6x^5) = -1/2

Answer:
no
Step-by-step explanation:
Similar triangles have angles with the same measures.
angles in the first triangle are 50°, 60°, 70°.
angles in the second triangle are 50°, 50°, 80°.
The angles do not have the same values, so the triangles cannot be similar.

<em>Comment on the question</em>
When 2 of the three angles are different, the third angle cannot make the triangles similar. We don't even need to compute the third angle to answer this question.
Answer:
The area of the shaded region is 7π square centimeters.
Step-by-step explanation:
Note that Circle B has a radius of 3 cm, and the two smaller circles, Circles O and C, both have a radius of 1 cm.
The area of a circle is given by:
Therefore, the area of Circle B, the entire circle, is:
The area of Circle O is:
And likewise, the area of Circle C is:
The area of the shaded area is the area of the Circle B subtracted by the area of Circles O and C. Hence:
Substitute and evaluate:
The area of the shaded region is 7π square centimeters.
