Answer:
8
Step-by-step explanation:
1+3 is 4
16÷4 is 4
4+4 is 8
X= 13.5
Every triangle equals 180 degrees. 23+23= 46. 46 - 1= 45. Then you solve the equation 10x+45=180 which would equal, 13.5.
Use the sum of angles's trigonometric identity formula:
cos(A+B)=(cosAcosB-sinAsinB)
x+y=4cos(t+π/6)+2sint=4(cost*cosπ/6-sint*sinπ/6)+2sint
recall that cosπ//6=√3/2, and sinπ/6=1/2:
4(cost*cosπ/6-sint*sinπ/6)+2sint=4[(√3/2)cost-(1/2)sint]+2sint
simplify:2√3cost-2sint+2sint=2√3cost
Natural selection is the process of nature selecting the fittest animals to survive and/or thrive, making the weaker ones die out. Over time, the animals with the stronger traits will evolve and adapt to its needs.
