If a 4 sided figure has 360°...for each side we add, we add 180°.
you have a 7 sided figure (360° + 3(180°) = 900°)
adding up your angles (781) and subtract it from 900 =
x = 119°
Answer:
26/52 or 1/2
Step-by-step explanation:
There are 13 cards per suit therefore there must be 26
38.9 is the answer. because it is rounded to the nearest tenth.
Answer:
x = 7 and 3/2
Step-by-step explanation:
We can say:
x - 7 = 0 and 2x - 3 = 0
<em>Lets solve for x - 7 = 0 first:</em>
Add 7 to each side of "="
=> <u>x = 7</u>
<em>Now lets solve for 2x - 3 = 0</em>
First add 3 to each side of "="
=> 2x = 3
Now divide each side by 2
<u>=> x = 3/2</u>
Hope this helps!
Answer:
First term (a) =8
Common difference (d)= t2-t1
=12-8
=4
Now, sum of first 31th term (tn31) =n/2{2a+(n-1)d}
= 31/2{2×8+(31-1)4}
=31/2{16+(30×4)
=31/2(16+120)
=31/2×126
=31×63
Step-by-step explanation:
Similarly use 19 as (n) for the 19th term
