Answer:
length PQ = 8.9 m
Step-by-step explanation:
The picture below completes the question you asked. From the picture above RSTU is a rectangle . The two shaded square has a length of sides 8 m and 4 m respectively. The legs of the triangle is the sides of the 2 squares. Therefore, the triangle is a right angle triangle. The adjacent side is 4 m while the opposite side is 8 m.
Using Pythagoras theorem the hypotenuse of the triangle can be calculated below.
Pythagoras theorem
c² = a² + b² Therefore,
c² = 4² + 8²
c² = 16 + 64
c² = 80
square root both sides
c = √80
c = 8.94427191
c ≈ 8.9 m
length PQ = 8.9 m
Answer:
x =
Step-by-step explanation:
The bar above the 3 indicates the 3 is a repeating digit , that is
0.3333....
We require 2 equations with the repeating digit placed after the decimal point
let x = 0.3333... (1)
Multiply both sides by 10 )
10x = 3.3333... (2)
Subtract (1) from (2) thus eliminating the repeating digits
9x = 3 ( divide both sides by 9 )
x = =
