I cant see the task... You need to put it on here
Answer:
51ft, 17ft, 39ft
Step-by-step explanation:
longest = x
2nd = 
x
3rd = x - 12
P = 107
a + b + c = Perimeter
x + x + x - 12 = 107
x -12 = 107
x = 119
x = 51
x = 17
x - 12 = 39
96 - 4.5y - 3.2y = 5.6y + 42.80
96 - 7.7y = 5.6y + 42.80
96 = 5.6y + 42.80 + 7.7y
96 = 13.3y + 42.80
96 - 42.80 = 13.3y
53.2 = 13.3y
4 = y
hope that helps, God bless!
The answer would be 66.5 sq :)!
Answer:
the question is incomplete, below is the complete question
"ress the following complex numbers in rectangular form. Show how you get the answer and use a calculator to verify your answer. E.g. 2 pts for 2∠30°=2(cos30°+jsin30°)=1.73+j, 1 pt for 2∠30°=1.73+j. Same grading criteria as 1.4. (a) Z1=5eⁱ³⁰ (b) z2=−3 ∠(−45°) (c) z3=2∠(−90°)
answer
a.Z1=4.33+j2.5
b. Z2=-2.12+j2.12
c.Z3=-2j
Step-by-step explanation
note that
Z=reⁱⁿ=r(cosπ+jsinπ)
hence from Z1=5eⁱ³⁰ wen have
Z1=5(cos30+jsin30)
Z1=5(0.8660+j0.5)
Z1=4.33+j2.5
b.also from z=r∠(π)=r(cosπ+jsinπ)
Hence,
z2=−3 ∠(−45°)=-3(cos(-45)+jsin(-45))
Z2=-3(0.7071-j0.7071)
Z2=-2.12+j2.12
c. z3=2∠(−90°)=2(cos(-90)+jsin(-90))
Z3=2(0-j)
Z3=-2j
