(not drawn to scale)

Given That X = 7.4 M And = 32, Work Out Bc Rounded To 3 Sf.(not Drawn To Scale)

Answers

Answer 1

Answer:

BC ≈ 11.8 m

Step-by-step explanation:

using the tangent ratio in the right triangle

tanΘ = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{x}{BC}[/tex] , that is

tan32° = [tex]\frac{7.4}{BC}[/tex] ( multiply both sides by BC )

BC × tan32° = 7.4 ( divide both sides by tan32° )

BC = [tex]\frac{7.4}{tan32}[/tex] ≈ 11.8 m ( to 3 sf )

The angle that is vertical (opposite) with ∠CXD = ∠AXB

Answer:

  ∠AXB or ∠PXQ or ∠AXQ or ∠PXB or ...

Step-by-step explanation:

A vertical angle is formed from the rays that are opposite the rays that form the original angle.

__

opposite rays

The rays forming angle CXD are rays XC and XD. The ray opposite XC will have end point X, and can be named by either of the two points shown on the ray: A or P. That is, rays XA and XP are opposite ray XC.

Similarly, rays XB and XQ are opposite ray XD.

vertical angle

The vertical angle can be named using either of the first pair of opposite rays with either of the second pair:

  ∠AXB, ∠PXB, ∠AXQ, ∠PXQ

Of course, the ray names can be reversed in the angle names:

  ∠BXA, ∠BXP, ∠QXA, ∠QXP

Altogether, there are 8 ways to name the vertical angle to ∠CXD.

Answer:

x ≈ 11.3

Answers

Answer:

Not similar

Step-by-step explanation:

If you have scratch paper, its best to label the angles and sides given. You can also rotate the orientation of one of the triangles if that helps visually.

First lets look at the sides.

Notice the common factor between side AB and side XY.

14/7=2

Notice the common factor between side AC and side XZ.

22/11=2

So far so good right? Well, IF these triangles are similar, that means that angle X must correspond to angle A. Since corresponding angles of similar triangles are equal to each other, lets check of angle X is equal to angle A.

Angle X = 29 degrees

Angle A = 28 degrees

28 does not equal 29 degrees. Therefore, the triangles are not similar. If angles X and A were equal, than the triangles would have been similar due to the Side-Angle-Side rule (SAS).

Therefore,  AD and DC will be = 1.5cm segments each.  

We are given C as the midpoint of segment DB.

So CB = 1.5cm.

The representation of the line segment is:

A-----------D------------C-------------B

     1.5           1.5            1.5

Since AD, DC and CB are each 1.5cm segments. Then the equation will be:

Question 7:
g is 60% of h
f is a third of g
Write the ratio f g h in its simplest form.

Answers

The ratio of f to g to h is:

1:3:5

How to write the ratio?

First, we know that g is the 60% of h, then we can write:

g = 0.6*h

Now we can write the 0.6 as a fraction, then 0.6 = 3/5.

g = (3/5)*h

So we can write:

5*g = 3*h

So the ratio of g to h is 3:5

Now, we know that f is a third of g:

f = (1/3)*g

3f = g

So the ratio of f to g is:

1:3

notice that the value that represents the proportion of g is 3 in both ratios, so we can just write:

The ratio of f to g to h is:

A trinomial is a polynomial consisting of three terms or monomials.

Given polynomial:

Taking -3x as common, we get

=-3x(x²+6x+8)

Now, by factorization

=-3x (x²+4x+2x+8)

= -3x[x(x+4) + 2(x+4)]
