The missing length of the right angled triangle can be calculated using Pythagorean Theorem as shown below:

Where,
a = x cm
b = 11 cm
c = 16 cm
Thus:






(nearest tenth)
Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (2, 4) ← 2 points on the line
m =
= 
2(x-1)=42
2x-2=42
2x=44
X=22
