Answer:
x = 48
Step-by-step explanation:
The sum of the angles in a pentagon is 540°, so you have ...
90° +100° +110° +2x° +3x° = 540°
5x = 240 . . . . . . . divide by °, subtract 300
x = 48 . . . . . . . . . divide by 5

<em>Additional comment</em>
The sum of angles in a convex n-gon is (n -2)×180°. For a pentagon, that's 3×180° = 540°.
I can help a bit. But I might don't know some though.
Answer:
Angle 2 is corresponding angle to angle 6 because they are in matching corners
Step-by-step explanation:
When two parallel lines are crossed by another line (transverse line), the angles at matching corners are congruent and are called corresponding angles.
In the question, other corresponding angles are 1 and 5, 7 and 3 and 8 and 4
Answer:
$9891.23
Step-by-step explanation:
The formula for future value of annuity due is:
Where,
- FV is the future value of the annuity (what we need to find)
- P is the periodic payment (here it is $400)
- r is the interest rate per period (here 13% yearly interest is actually percent per period(quarter))
- n is the number of periods (here the annuity is for years, which is periods, since quarterly and there are 4 quarters in 1 year)
Substituting all those values in the equation we get:
Hence, the future value of the annuity due is $9891.23
