(can someone please help no one has been helping me...)The picture shows a triangular island: A right triangle is shown with an acute angle equal to 45 degrees. The length of the side of the triangle opposite to the acute Which expression shows the value of c? (1 point) b over tan 45 degrees b over cos 45 degrees a cos 45° a tan 45°

10.4 inches

step-by-step explanation:

2x2x2.6

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2
