We can Notice From the Figure that the Sides of the Triangle are Equal.
If a Triangle has all of its Sides Equal, then it is an Equilateral Triangle
We know that In an Equilateral Triangle all Angles are Equal to 60°
⇒ (2x - 4) = 60°
⇒ 2x = 60° + 4°
⇒ 2x = 64°
⇒ x = 32°
4•4 -1•1 = 16-1 = 15 square inches

Step-by-step explanation:
761-331=430
Answer:
r is the common ratio (in geometric sequence)
d is the common difference (in arithmetic sequence)
n is the term number
a1 is the value of the first term
an is the value of the nth term
Step-by-step explanation:
arithmetic sequence formula:
an=a1+d(n-1)
geometric sequence formula:
an=a1•(r)^(n-1)
