Answer:
x = 40
Step-by-step explanation:
Angles SRT and STR are congruent, so they have the same measure.
The measure of <SRT is 20, so the measure of <STR is also 20.
Angles STR and STU form a linear pair. Two angles that form a linear pair are supplementary, so their measures add up to 180.
m<STR + m<STU = 180
20 + 4x = 180
4x = 160
x = 40
Answer:
452.39 mm^2
Step-by-step explanation:
Area of a circle = 
r^2
Here r = 12mm
Therefore, Area= x 12^2 = 452.389342...
Round to required degree of accuracy = 452.39mm^2
Hope this helps

im not sure about 96
Step-by-step explanation:
length of side = 36 cm
let x be the side of the square then x + 8 is the side of the triangle
perimeter of square = 4x and
perimeter of triangle = 3( x + 8 ) + 4 = 3x + 24 + 4 = 3x + 28
equating the perimeters
4x = 3x + 28 ( subtract 3x from both sides )
x = 28
length of side of triangle = x + 8 = 28 + 8 = 36 cm
