Answer:
1) 20 degrees. 2)60 degrees. 3)30 degrees
Step-by-step explanation:
For number 1, there are 180 degrees in a triangle. Since we already know all the measures, we can just make an equation.
90+31+3x-1=180
120+3x=180
-120 -120
3x=60
x=20
for number 2, the traingle must be equilateral because they all have the same measure. That's why it's 60 because 60*3=180
Last one:
Same as 1st one. Make an equation: x+3x+2x=180
Combine like terms
6x=180
x=30

Answer:
The value of y is 4 cm.
Step-by-step explanation:
First find the lengths of each side (square root of 256 is 16, so each side of the bigger square is 16 cm) of each square (square root of 64 is 8, so each side of the smaller square is 8 cm). Then, since each y value is the same and equal, 16 (length of one side of bigger square) minus 8 (length of one side of smaller square), divided by 2 (because there are 2 y values per length), you get 4 cm. Hope that helps!
Here are the values of the first 5 terms of 3 sequences: : 30, 40, 50, 60, 70, . . . : 0, 5, 15, 30, 50, . . . : 1, 2, 4, 8, 16,

Answer:
1,2,4,8,16.
Step-by-step explanation:
they are a square root of 2 for each question. it will eventually get up higher then additive.
