Answer:
x= 79° y= 22°
Step-by-step explanation:
x is the same as 79
79+79= 158
180° in a triangle
180-158= 22°
Answer:
-72
Step-by-step explanation:
-32 + (2-6)(10)
PEMDAS
Parenthases first
(-4)(10)
multiply together
(-40)
Then just add the -32 and since a negative plus a negative is always negative the answer is going to be negative
-32 + (-40)
= -72
Answer:length = 9 width = 3
Step-by-step explanation:
length =3x
width = x
perimeter = 24 = 3x + x +3x + x = 8x
8x = 24 therefore x = 3
so length = 3(3) = 9 width = 3
so perimeter = 3+9+3+9 = 24
