Answer:
140° and 40°
Step-by-step explanation:
let x be one angle then the other is x - 30
Since the angles are a linear pair, theis sum is 180° , then
x + x - 30 = 180, that is
x - 30 = 180 ( add 30 to both sides )
x = 210 ( multiply both sides by 2 to clear the fraction )
3x = 420 ( divide both sides by 3 )
x = 140
and x - 30 = (140) - 30 = 70 - 30 = 40
The 2 angles are 140° and 40°

She needs to lay 11 slabs on each row to make a square
<h3>How to determine the number of slabs in each row?</h3>
The total number of slabs is given as:
Total = 121 slabs
Let this represent the area of the slab.
The area of a square is calculated as:
Area = Length^2
Substitute the known values in the above equation
Length^2 = 121
Take the square root of both sides
Length = 11
Hence, she needs to lay 11 slabs on each row to make a square
