Answer:
the size of interior decagon is 70
Answer:
Yeah a triangle can have any measurements as long as it makes sense. Your not gonna put the mesurment 8 on the shortest side but the longest, and then the next longest will be 4, and then 3 as the shortest.
Step-by-step explanation:
You'd be lookin for a scalene triangle, Acute triangle, or obtuse triangle, (I'm not so sure about a right triangle, but you might be lookin at that too)
I hope this helps!!!!

Answer:

Step-by-step explanation:
<h3>Arithmetic sequence:</h3>

6th term is 14 ⇒ 
a + (6 - 1)d = 14
a + 5d = 14 --------------(I)
14th term is 6 ⇒
a + (14-1)d = 6
a + 13d = 6 ----------------(II)
Subtract equation (II) from equation(I)
(I) a + 5d = 14
(II) a + 13d = 6
<u>- - -</u>
-8d = 8
d = 8 ÷(-8)

Plugin d = -1 in equation (I)
a + 5(-1) = 14
a -5 = 14
a = 14 + 5
20th term:

= 19 - 19

Answer:
23n +5
Step-by-step explanation:
break down the expression into parts
5 more is +5
product is multiplication of 23 and n so 23n
then put it together
