[Note that you don't have to evaluate k to solve the problem]

x = \frac{kuv}{(u+v)}

That means that

x \frac{(u+v)}{(uv)} = k, a \: constant

So, you want xsuch that

x \frac{(3+3)}{(3 \times 3)} = 3 \frac{(3+1)}{(3 \times 1)}

x=6

ZN
solmaris [256]

Given tangent, ZN, to the circle and the arc \widehat{ZMB} = 280°, we have that

the angle formed by the chord BZ and the tangent ZN, ∠BZN is 50°

<h3>Which method can be used to find ∠BZN?</h3>

The given parameters are;

A tangent to the circle O = ZN

m \widehat{ZMB}} = \mathbf{280^{\circ}}

Required:

Angle ∠BZN

Solution;

Please find attached the drawing of the circle and tangent

From the drawing, we have;

∠BOZ = 360° - 280° = 80°

ΔBOZ is an isosceles triangle, which gives;

∠BZO = ∠ZBO

\angle BZO = \dfrac{(180^{\circ}- 80^{\circ}) }{2} = \mathbf{50^{\circ}}

∠OZN = 90° (by definition of a tangent)

∠OZN = ∠BZO + ∠BZN

∠BZN = ∠OZN - ∠BZO

Which gives;

∠BZN = 90° - 40° = 50°

  • The measure of angle ∠BZN =<u> 50°</u>

Plz plz helpppppp0pp
postnew [5]

Answer:

28cm

Step-by-step explanation:

Hi!

Let's find the area of the rectangle (we can form) and then tack on the area of the triangles.

We have 4 * 3 = 12. So the first area is 12.

Now, the triangles. We see that they will have base 4, and leg 2.

Using the Pythagorean Theorem:

4² + 2² = 20. √20 = 2√5. That won't really matter however, because we will multiply 4 by 2 to find the area.

4 * 2 = 8

The same will happen on the other side:

4 * 2 = 8 (note that we could've created a rectangle out of the triangles, but that would give us 16 too.)

8 + 8 = 16.

16 + 12 = 28

Thus, the area is 28 cm.

Hope this helps!
