The surface area of that pyramid is 192 cm^2
Answer: 1/3
Step-by-step explanation:
1 divided by 3 = 1/3
Angles on a straight line add up to 180 degrees so
45 + 3x = 180
Subtract 45 from both sides to remove the 45 on the left
3x = 135
Then divide both sides by 3
x = 45
Answer is X = 45
3/1 is your slope for that
(13 + 20) + 15 = 13 + (20 + 15)
