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
Answer:
Step-by-step explanation:
12.8 feet
If you divide 144 by three you get 48. Then when you subtract one from 48 you get 47. When you add one to 48 you get 49. So the three consecutive numbers are 47, 48, 49
Answer:
D) 2
Step-by-step explanation:
it think it's D because the size of the triangle was doubled
2 was matched to 4 and
1 was matched to 2
