Multiply the length 7 tiles by the width of 2 tiles to get the area of 14 tiles
We know that
applying the law of cosines
a² = b²+ c²<span> – 2*b*c*cos(A)
cos (A)=[b</span>²+c²-a²]/[2*b*c]
in this problem
a=10
b=17
c=18
so
cos (A)=[17²+18²-10²]/[2*17*18]-----> cos (A)=0.8382
A=arc cos (0.8382)-----> A=33.05°-----> A=33°
the answer is
33 degrees
1.1, 0.10299, 0.1038, 0.9 im pretty sure
To a higher number the six changes value in this number above
