Step-by-step explanation:
in the diagram it is clearly shown that corresponding angles are congruent and all the sides are in 1/2 ratio
Answer:
x=3.8
Step-by-step explanation:
7 and 3/5 over 2 is equivalent to 3.8. x is over one so you just use that number as the answer
Answer:
9in 12in 15in
Step-by-step explanation:
Answer:
h = 3
k = -2
r = 2
Step-by-step explanation:
The numbers inside the parentheses are the opposites of the values h and k.
For the radius, we look at the constant on the other side of the equation and square root that. In this case, the square root of 4 is 2.

Answer: 1440 degrees</h3>
===================================================
Explanation:
See the diagram below. It shows there are 10 sides, so n = 10.
We'll plug this value of n into the formula below to find the sum of all ten interior angles
S = sum of interior angles
S = 180(n-2)
S = 180(10-2)
S = 180(8)
S = 1440 degrees
---------------
A different approach:
Let's assume this polygon is a regular polygon. This means each angle is congruent to one another.
We have n = 10 sides, so each exterior angle is E = 360/n = 360/10 = 36 degrees.
Each interior angle adjacent to this 36 degree exterior angle is
180-E = 180-36 = 144 degrees
Since we have 10 equal angles of 144 degrees each, so overall the interior angles add to 10*144 = 1440 degrees
Side note: if this polygon is not a regular polygon, then this section does not apply. You would use the first method instead.
