Answer:
Total Surface Area = 2(LW+WH+LH)
Step-by-step explanation:
Surface Area of;
face 1 = LW
= 20 × 10
=200
face 2 = WH
= 10×12
= 120
face 3 = LH
= 20×12
=240
TSA = 2(200+120+240)
=560×2
=1120
Answer:
For the First Question:
x = 61
y = 61
For the Second Question:
x = 12
y = 7
Step-by-step explanation:
Second question:
96 = 11y + 19
11y = 77
y = 7
96 = 8x
x = 12
Answer:yes they do
Step-by-step explanation:
Answer:
A.) NM= x
C.) LM = x√2
E.) tan (45°) = 1
Step-by-step explanation:
If the legs are both x, then the hypotenuse is equal to 
Therefore, LM=
is correct and MN= x
