Answer:
The perimeter is 7 dm
Step-by-step explanation:
we know that
The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.
Let
c------> the length of the third side
case a)
1+c>3
c>2 dm
case b)
1+3> c
4 > c
rewrite
c<4 dm
The solution for c is the interval------> (2,4)
therefore
the value of c must be equal to
c=3 dm (because is an integer)
The perimeter is equal to
P=1+3+3=7 dm
The first angle is 76 and the second angle is 14. You can check this by doing 14+5=19 and then multiply that by 4.
Evaluate<span> the series by expanding the summation, then adding all of the values. 154 would be the answer.</span>
I don't know what the question is, but I may be able to help a little. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
Answer:
y=7/5x+7
Step-by-step explanation:
The slope is 7/5 and the y-intercept or b is 7.
Hope this helped :)
