Answer:
50 degrees
Step-by-step explanation:
We know that an inscribed angle in a circle is 1/2 the arc that it inscribes. So, therefore the arc is inscribed by the 25 degrees is 50. Assuming that the center of the circle is O, the center angle will be the arc measure. Knowing this, angle a is 50 degrees. If you're curious about all these theorems, they can be proved using similar triangles.
fyi, using the same logic, angle b is 25 degrees
Answer:
B. No

Step-by-step explanation:
-A right angle triangle has two complimentary acute angles and one right angle.
-
is usually one of the acute angles and is equivalent to 90º minus it's complimentary acute angle.
-Complimentary angles add up to 90º.
#For complimentary angles:

The two acute angles cannot have the same Cosine value.
Hence, she's not correct.
Answer:
equals what ie tablespoons lbs ??
Step-by-step explanation:
Answer:
Length
inches
Width
inches
Step-by-step explanation:
Let
= length of rectangle,
= width of rectangle
Given the area and the perimeter of the rectangle, we can write:

So:



Now, we can use substitution to find the value of
:



(Quadratic equation)
∴ 
We can use substitution again to find the value of 



∵ Length usually refers to the longer side of a rectangle, ∴ length
inches and width
inches.
Hope this helps :)
