Answer:
I believe h do 9 times 6. and u should get 54
Answer:
k= 5b-3/
4
Step-by-step explanation:
3−3k+7k=5b
(Combine −3k and 7k to get 4k.)
3+4k=5b
(Subtract 3 from both sides)
4k=5b−3
(Divide both sides by 4.)
k= 5b-3/
4
So in this case you have two equal side lengths, which means you have a 45,45,90 triangle. However to prove this you do the following…
Identify if it’s giving you hypotenuse, adjacent, or opposite side length.
In this instant, it’s giving an opposite and adjacent length.
Remember SOH CAH TOA
Because you have Opposite and Adjacent you use Tan and tan(x)= opp/adj
Tan(x)= 2root2/2root2
Isolate the x through the inverse of tan
To get x= tan-1(2root2/2root2)
And this gets you 45 degrees or .79 radians
Answer:
β = 140 - α
we know that the "missing" angle is 40° since 40 + 140 = 180
we also know that the total sum of angles in a triangle is 180
so β = 180 - 40 - α
or β = 140 - α
