PLEASE HELP WILL GIVE BRAINLIESTT

Mathematics
1 answer:
Evgesh-ka [11]3 years ago
3 0

Answer:

x = 135,

y = 45

Step-by-step explanation:

45 and y are vertical angles.  That means they are equal

y = 45

45 and x form a straight line which means they sum to 180

45+x = 180

Subtract 45 from each side

45+x-45 =180-45

x = 135

The surface area of a rectangular prism is 150 cm². If all the sides are tripled, what will the new surface area be?
DerKrebs [107]
SA=2(LW+LH+WH)
if all are trippled then

SA=2(3L3W+3L3H+3W3H)
SA=2(9LW+9LH+9WH)
SA=2(9)(LW+WH+WH)
SA=9(2(LW+WH+WH))
the SA will be multiplied by 9

150 times 9=1350

new surface area is$1350 <span>cm²</span>
