Answer:
I'm gonna go with the first choice because it's rational.
Step-by-step explanation:
Answer:
D. sin J = Cos L
Step-by-step explanation:
LK = √219² - 178² = 127.58
sin J = <u>LK/LJ</u> =127.58/219 = 0.58
Cos L = <u>Lk/LJ</u> = 0.58
sin L = 178/219 = 0.81
Cos J = 178/219 = 0.81
Tan J = 127.58/178 = 0.72
tan L = 178/127.58 = 1.40
Answer:
h = 2 cm
402 over 3.14 x (8) to the power of two. SImplifies to about the answer of 2
Answer:
to help, i will demonstrate the first problem. This is a right triangle. We know this because it is a 45-45-90 triangle.
Because of this we know that the sides are 2 and 2 (they must be equal).
Now we need the hypotenuse- the side across from the right angle (in other words, the diagonal line).
To do this we take 2 times the square root of two. This makes it 2.82.
