Answer:

Choice B is correct answer.

Step-by-step explanation:

From question statement, we observe that

Perpendicular = x

Hypotenuse = 10

∅  = 70°

We have to find the value of x.

Since we know that sin∅= perpendicular/hypotenuse

Putting the values in above formula,we get

sin70°= x/10

Multiplying above equation by 10,we get

10sin70° = (x/10)10

10sin70° = x

x = 10×.9396

x = 9.396≈9.4

Hence, the value of x is 9.4

Answer:

Second choice

Step-by-step explanation:

The unknown leg x in right triangle is opposite to the angle of the measure 70°.

Use the definition of the sine of the angle:

\sin 70^{\circ}=\dfrac{\text{opposite leg}}{\text{hypotenuse}}=\dfrac{x}{10}.

Hence,

x=10\sin 70^{\circ}\approx 9.4.

4. The length of a rectangle is one more than twice the width. The area is 105 in?.
Zanzabum

9514 1404 393

Answer:

  7 in

Step-by-step explanation:

For width w in inches, the length is given as 2w+1. The area is the product of length and width, so we have ...

  A = LW

  105 = (2w +1)w

  2w^2 +w -105 = 0

To factor this, we're looking for factors of -210 that have a difference of 1.

  -210 = -1(210) = -2(105) = -3(70) = -5(42) = -6(35) = -7(30) = -10(21) = -14(15)

So, the factorization is ...

  (2w +15)(w -7) = 0

Solutions are values of w that make the factors zero:

  w = -15/2, +7 . . . . . negative dimensions are irrelevant

The width of the rectangle is 7 inches.
