Plzzzzzzzzzzzzzzzzz help
andrew11 [14]

Answer:

7y8.9 ft²

Step-by-step explanation:

Easy way:

Rotate the triangle so that the 12.1 ft side in on the bottom becomes the base.

Drop a line from the top down perpendicular to the 12.1 ft base. That makes a right triangle.

sin 71 = height/13.8

0.9455 = height/13.8

height = 13.05 ft

Area = bh/2 = (12.1)(13.05)(0.5) = 78.9 ft²

4 consecutive odd integers add up to -200. Find the integers.
Alexeev081 [22]
Let
x = first odd integer
x + 2 = second odd integer
x + 4 = third odd integer
x + 6 = fourth odd integer

x + (x + 2) + (x + 4) + (x + 6) = -200
4x = -200 - 2 - 4 - 6
4x = -212
x = -53

Therefore, the four consecutive integers are -53, -51, -49, -47.
