Which statement is true?

1 answer:

7 0

The Correct answer is C. -14 + (-10) = -24 and 2 + (-28) = -26. When negative numbers are in play, the lower negative number is higher in value. So when solved -24 > -26

The bearing of Y from X is 63

zimovet [89]

Answer:

117°

Step-by-step explanation:

As per diagram:

∠NXY ≅ ∠XYZ as alternate interior angles since XN and YN are parallel and XY is transversal
m∠XYZ = m∠XZY = 63° since ΔXYZ is isosceles

Find the measure of ∠YXZ:

m∠YXZ = 180° - 2*63° = 54°

Find the bearing of Z from X:

m∠NXZ = m∠NXY + m∠YXZ = 63° + 54° = 117°

The volume of a sphere is 972(pi)ft3.

pav-90 [236]

Here are some simple equations that can be a life saver with this stuff :

vol of a sphere =

$v = \frac{3}{4} \pi \: {r}^{3}$

Circumference =

$2 \times \pi \times r$

sorry this might not be very helpful. I haven't don't this since last year. You basically have to work backwards. so plug in 972 for V and then do (3/4)×3.14.

then take the answer u got for ^^ and divide it by 2? not sure.

WILL MARK BRAINLIEST ANSWER!!!!!!! Quadrilateral KLMN is similar to quadrilateral WXYZ. Write a proportion that must be true for

snow_tiger [21]

Answer:

Since, In Quadrilaterals KLMN and quadrilateral WXYZ,

Sides Kl, LM, MN and NK are corresponding to the sides WX, XY, YZ and ZW respectively.

Also, If two shapes are similar the ratio of their corresponding sides must be same are in same proportion,

Here, Quadrilateral KLMN is similar to quadrilateral WXYZ,

Therefore,

$\frac{KL}{WX}=\frac{LM}{XY}=\frac{MN}{YZ}=\frac{NK}{ZW}$

Which is the required proportion that must be true for the given figure.
