Sin(α+β)=sin(α)cos(β)+cos(α)sin(β)
sin(α-β)=sin(α)cos(β)-cos(α)sin(β)
Answer:
112 cm²
Step-by-step explanation:
The surface area is the sum of the area of all the 6 faces, that is
area = area of 2 purple + area of 2 green + area of 2 orange
= 2(4 × 8) + 2(2 × 8) + 2(4 × 2)
= (2 × 32) + (2 × 16) + (2 × 8)
= 64 + 32 + 16
= 112 cm²
Volleyball- 27% 21% 49%
Swimming- 37% 14% 51%
Total- 64% 36% 100%
Using the property of logarithms log(a)b = x => a^x = b so we get
(2x-4)^4 = 16
(2x-4)^4 = 2^4 because the exponents are equal so this equation will be right than the bases will be equals too so than
2x -4 = 2
2x = 6
x = 6/2 = 3
x = 3
hope this will help you
