Answer:
6+10+14+18+22+26
Step-by-step explanation:
Let n =1
4(1) +2 = 6
Let n = 2
4(2) +2 = 8+2 = 10
Let n =3
4(3) +2 = 12+2 = 14
Let n= 4
4*4+2 = 16+2=18
Let n=5
4*5+2 = 20+2 =22
Let n=6
4(6)+2=24+2=26
Sum these together
6+10+14+18+22+26
It makes a 74 degree angle.
The sides of the triangle that are given are the side adjacent to the angle the ladder makes with the ground and the hypotenuse of the triangle.
adjacent/hypotenuse is the ratio for cosine:
cos x = 7/25
To solve this, we will take the inverse cosine:
x = cos⁻¹(7/25) = 73.7 = 74
