Answer:
measure of each base angle = 80 each angle
measure of vertex angle = 20
Step-by-step explanation:
x=base angle
2x+ x/4= 180
Multiply everything by 4 to eliminate the fraction
8x+x = 720
9x=720
x=80
80/4=12
<h3>
Answer:</h3>
4, 8, 8
<h3>
Step-by-step explanation:</h3>
At each node, three faces meet. One is square (4 sides); the other two are octagons (8 sides). Hence the tiling can be named with three numbers: 4, 8, 8.
Step-by-step explanation:
The first set is equivalent.
We obtain the right-hand side by swapping places of the terms.
answer
system : 8L+ 4S = 120
L + S = 20
There are 10 small packs and 10 large packs
step by step answer :
to form the two systems, we have to determine the catagories of the 2 equations : one for money and one for the no of packs
after forming the two equations we simply put the numbers in the same order put above on the calculator ( mode 5:1) and the calaculator will answer it in seconds . 10 small packs and 10 large packs.
To check your answer , substitute the letters with their values and if both equations gave you the same value at the end then your answer is correct!
