Answer:
The perimeter of triangle CDE is 34.
Step-by-step explanation:
To find the perimeter of a triangle, you have to add all the sides together, since this looks like a isosceles triangle, you would make side ED also 12 and then just add them all together.
12+12+5+5= 34.
Order of operations, the order in which to do them
pemdas
parenthasees
exponents
multiplication or division (whichever comes first)
addition or subtraction (whichever comes first)
so
inside parenthaees first
20x/5=4x
now we has
[4x*(-x)]+3
multiply
4x*-x=-4x²
now we has
[-4x²]+3
-4x²+3 is the eavlauted form
Answer:
e=g = 126 degree
Step-by-step explanation:
e = g (opposite angles's property)
g+ b = 180 ( supplementary angles's property)
b = 54 degree (opposite angles's property)
-> g = 180-54 = 126
-> e = 126 degree
