Answer:
7 is the GCF of 21a and 28y
Step-by-step explanation: they both can be divided by 7!
7(21a/7 + 28y/3) = 7(3a + 4y)
the slash is a division symbol!
Check the picture below.
bearing in mind that an angle bisector segment will cut the angle A in two equal halves, thus θ will be half of A.
Answer:
The perimeter of the polygon is 48 cm.
Step-by-step explanation:
Given:
To find the perimeter of the polygon, we need to find the lengths of the AB, BC, CD and DA
Since, and to find the length, from circle theorem, "Two tangents from an external point to a circle are always equal in length".
From this statement we shall conclude,
The length of
The length of
The length of
The length of
Thus, the perimeter of the polygon is
Hence, the perimeter of the polygon is 48 cm.
