he diagram shows a ladder leaning against a vertical wall. The ladder stands on horizontal ground. The length of the ladder is 6 m. The bottom of the ladder is 2.25 m from the bottom of the wall. A ladder is safe to use when the angle marked y is about 75°. Is the ladder safe to use? You must show all your workin

78.59 is the mean

step-by-step explanation:

11

step-by-step explanation:

32.50-7.50=25

225/25=11

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
