Answer:
in this case you can use protector also but
there is another way
Step-by-step explanation:
as we know sum of a triangle is 180 degree
so let's D= 2x,x
35+x+2x=180
3x+35=180
3x=180-35
3x=145
x=145÷3
x =46.06
-4^3 is -64. so 64 is the opposite of -64
So assuming that x2=x^2 and not 2x
3(7+2^2)
3(7+4)
3(11)
33
The perimeter is 32 because if you add up all the sides you get 32 and 8 times 4 is 32
