Solve for x in the triangle
a 1.7
b 2.6
c 2.7
d 3.0

A

Step-by-step explanation:

Given 2 sides and the included angle use the Cosine rule to solve for x

x² = 1.6² + 1.1² - (2 × 1.6 × 1.1 × cos78° )

    = 2.56 + 1.21 - ( 3.52 × cos78° )

   = 3.77 - 0.7318

   = 3.0382

Take the square root of both sides

x = = 1.7 → A

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
