Help me with this question ​

Answers

Answer:

37.2

Step-by-step explanation:

when you turn the small triangle LMN to its right angle to cover the right angle of KLM, you find that they are similar triangles.

therefore the corresponding side lengths are at the same ratio.

LM/KM = MN/LN

LM = 24

MN = 13

we can get LN via Pythagoras of the small triangle

LN² + MN² = LM²

LN² + 13² = 24²

LN² = 24² - 13² = 576 - 169 = 407

LN = sqrt(407) = 20.174241

now back to our main problem

24/KM = 13/sqrt(407)

24×sqrt(407)/13 = KM = 37.2

In right triangle ABC with the right angle at C, sin A= 2x + .1 and cos B = 4x - .7. Determine and state the vaule of x.

Answers

Imagine \angle A at the top of the triangle and \angle B at the bottom. (or used the attached picture for reference)

\sin A= (opposite)/(hypotenuse)

\cos B = (adjacent)/(hypotenuse)

One thing to note, however, is that the side opposite \angle A is the same side as the one adjacent to \angle B! Thus \sin A=\cos B.

Substitute these values for 2x+0.1 and 4x-0.7 and solve.

 4x-0.7=2x+0.1 \n 4x=2x+0.8 \n 2x=0.8\n \boxed{x=0.4}

your order comes in for new protective eye wear. you order five and a half dozen. how many individual protective eye wear should you have recieved

Answers

 You should have received  33 pairs of protective eyewear

To Check This:
1 dozen = 12
1/2 dozen = 6
5 dozen = 60

12x5=60+6=66
66 / 2 = 33 because a pair equals 2
