Answer:
Hi there!
The correct answer is: 20
Step-by-step explanation:
knowing this a right triangle you can solve this problem in two ways
Method One: Pythagorean Theorem
a^2 + b^2 = c^2 then plug in the values
(12)^2 + (16)^2 = c^2 this will come out to be 400 = c^2
square root both sides and you get c = 20
Method Two: Pythagorean Identities
if you ever learned the Pythagorean identity 3,4,5
this triangle is indeed a 3,4,5 triangle it's just that each side is multiplied by the factor 4
so in this case since you know the missing side should be 5 you just multiply 5 by 4 and you get 20
A and b can do a piece of work in 12 days. If a alone have to finish the job among b and c so
A and b=12
A (24 days alone without b)
So if b and c 15 days and c 20 days. If a have to do all I would add 24 and 15 and 20 which would be 59 days
I am assuming you mean 4/7 as the sine or cosine cannot be higher than 1.
Lets find <span>θ,
</span>
θ = [sin-1](4/7) = 34.85 °
But lets take into account that this value is the equivalent in Quadrant I.
If Θ lies in Quadrant II , then θ = 180 ° - 34.85 ° = 145.15 °
So cosθ = cos (145.15) = -0.821
