The first thing you must do is find KL. You use a^2 + b^2 = c^2 to do that.

Then you find the various sines and cosines and Tangents of the angles involved.

Step One

Find KL

a^2 + b^2 = c^2

c = 219

b = 178

a = ??

219^2 = 178^2 + a^2

47061 = 31684 + a^2

a^2 = 48061 - 31684

a^2 = 127.97

Step Two.

Find the sines and cosines of J and L

Choice A

Sin(J) =opposite/hypotenuse =   127/219 = 0.5799

Cos(L) = adjacent/hypotenuse = 127/219 = 0.5799

Conclusion Sin(J) = Cos(L) A is not true. Neither is bigger than the other.

Choice B

Choice B does exactly what Choice A did. The Sin of L is the same thing as the cos(J).

Choice C

C can't be true.

Tan(J) = opposite / Adjacent. = 127/178

Tan(L) = opposite / Adjacent = 178/127

One is larger than 1 and the other one is less than 1. They use the same values but in a different order.

D

We discussed this for choice A. So D is the correct answer

First you need to find out what K and L's angle is

Step #1: Finding L's angle number

to do this you are going to subtract  219-178=?

answer should be 41.

Step #2: Desiding if J is Larger than L

Is 219 Larger than 41? or is 41 larger than 219?

Six less than twice a number, x, is 38. What is the value of x?<br> 76<br> 16<br> 70<br> 22
uranmaximum [27]

Answer:

22

Step-by-step explanation:

2x -6 = 38

Add 6 to each side

2x-6+6 = 38+6

2x + 44

Divide each side by 2

2x/2 = 44/2

x = 22

Help I’ll mark brainliest
lakkis [162]

Answer:

12.04m = l

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 =c^2

where a and b are the legs and c is the hypotenuse

12^2 + 1 ^2 = l^2

144 + 1 = l^2

145 = l^2

Take the square root of each side

sqrt(145) = sqrt(l^2)

12.04159458 = l

To the nearest hundredth

12.04m = l
