Answer:
80 units
Step-by-step explanation:
The star has 10 sides. If each side is 8 units, then the perimeter is 10(80) because the perimeter is the sum of the lengths. With each length being 8, you could add 8 to itself 10 times, but it is faster to multiply.
Answer:
x=0.75
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
=>sec A cosec A - tan A - cot A
=>(1/sinAcosA)-(sinA/cosA)-(cosA/sinA)
You get the LCM as sinAcosA then it becomes
=>(1-sin^2(A)-cos^2(A)) /sinAcosA [1-sin^2(A)=cos^2(A)]
=>(cos^2(A)-cos^2(A))/sinAcosA
=>0/sinAcosA
=>0
