Supplementary angles, when added, equal 180 degrees
so < A + < B = 180...and if < A = 80
80 + < B = 180
< B = 180 - 80
< B = 100 <==
Answer:
triangular pyramid
Step-by-step explanation:
Let's make the central triangle the "base", or the bottom face, of our polyhedron. Try to visualise what will happen if we fold up the three triangles so that their top vertices meet at the center top (see diagram).
If we can do that, we'll see that it's a pyramid with a triangular base, so it's a triangular pyramid.
Answer:
• exterior angle of a triangle is equal to sum of opposite interior angle
(6x-7) = (103-x) + 2x
6x-7 = 103 - x + 2x
6x-7 = 103 + x
6x - 7 - x -103 = 0
6x - x - 110 = 0
5x - 110 = 0
5x = 110
x = 110/5
x = 22
as exterior angle is (6x-7)
= 6 × 22 - 7
= 125
-> Exterior angle is 125°
pls do mark as brainliest. . . ☺
One pound is 16oz. So you take 54 and minus it by 16 until you get something less that 16. Then you take how many times you subtracted it, and that is how many pounds. Then you take the "leftover" number and they you have your answer.
so Sarita used 3 pounds and 8 oz.
It is 3x=4. If u need anymore help then that is cool
