Parallelogram has two pairs of parallel sides. Obviously the left and lights are well and grandpa parallel because they’ll give me other thing that marks them is that they both have the same one that means that the sides that they intersect, the top and the bottom, or also parallel because they are the same distance
Your question isn't clear. But I infer this is the clear rendering of it;
How many diagonals does a polygon have with 5 sides, but with 6 sides?
Answer:
a. For 5 sides= 5
b. For 6 sides= 9
Step-by-step explanation:
Remember, this is the formula to calculate the number of diagonals of a polygon;
n (n-3) / 2 where n is the sides.
Thus,
for 5 sides= 5 (5-3) /2
= 5 (2) /2 = 10/2= 5
for 6 sides= 6 (6-3) /2
= 6 (3) /2 = 18/2= 9
You have to put 2 in for ’x’
Answer:
Step-by-step explanation:
By the Triangle Angle-Sum Theorem, the angles of a triangle add up to equal 180, regardless of the size of the triangle. We are given the angle measures, so adding them together and setting them equal to 180 is
60 + 3x + x + 20 = 180 and, combining like terms,
4x + 80 = 180. Subtracting 80 from both sides,
4x = 100 so
x = 25
