Answer: a=145 +22=167
Step-by-step explanation:
1. ABC and ADE are similar triangles because because its measures are proportional
2. x=4 because AD is twice AB
3. AE is twice the size of AC
A because if you think about it 5 less witch is - than twice witch is 2 then add you’re x
Sin(pi/4) = 1/sqrt(2)
csc(pi/4) = sqrt(2)
csc^2(pi/4) = 2
-csc^2(pi/4) = -2
I think this is right but, 0.000345 = 3.45x10^-4
