Answer:
Step-by-step explanation:
The above is a right angled triangle
So you take the longest side
9.4^2 - 6.8^2
88.36- 46.24
sqrt of 42.12
6.4899
To the nearest tenth of a degree = 6.56.5ft
Answer:
y = 6
Step-by-step explanation:
To write the equation of a line, calculate the slope between points (-4,y) and (-2,8). Substitute m = 1 and solve for y.

Answer:
x = ± 
Step-by-step explanation:
3x² + 7 = 28 ( subtract 7 from both sides )
3x² = 21 ( divide both sides by 3 )
x² = 7 ( take square root of both sides )
x = ± 
that is x = -
, x =
