Answer:
SA = 124 cm²
Step-by-step explanation:
The lateral surface area is the area of all sides besides that base, so 93 cm² is the sum of 3 sides of the tetrahedron.
93/3 = 31 cm² per side, there are 4 sides, so 31(4) = 123 cm² is the total surface area
5x+2=47 subtract 2 from both sides
5x=45 divide both sides by 5
x=9
