<h3><u>To find value of x</u></h3>

<u>Formula applied:</u>

Exterior angle=Sum of interior angles

Answer:

  • x=66⁰+45⁰

  • x=<u>1</u><u>1</u><u>1</u><u>⁰</u><u>✔</u>
<h3 />

<h3><u>To find value of z:</u></h3>

<u>Formula applied:</u>

Exterior angle=Sum of interior angles

Answer:

  • 119⁰=43⁰+z⁰

  • 119⁰-43⁰=z⁰

  • z⁰=<u>76</u><u>⁰</u><u>✔</u>

<h3><u>To find value of y:</u></h3>

  • ∠1+66⁰=180⁰(L.P)

  • ∠1=180⁰-66⁰

  • ∠1=114⁰

<u>Formula</u><u> </u><u>used:</u>

Sum of angles of a triangle =180⁰

Answer:

  • ∠ 1+30⁰+y⁰=180⁰

  • 114⁰+30⁰+y⁰=180⁰

  • y⁰=180⁰-144⁰

  • y⁰=<u>36⁰</u><u>✔</u>

the time it takes to fly from los angeles to new york varies inversely as the speed of the plane. if the trip takes 6 hours at 9
natima [27]
Inverse variation means y=k/x  (direct variation is y=kx) so we can use the info given to find the constant k

y=k/x

6=k/900

k=6(900)

k=5400 so the equation is:

y=5400/x  or more accurately for this problem

t(v)=5400/v  then:

t(800)=5400/800

t(800)=6.75 hours

Anni [7]

Answer:

It's proved below

Step-by-step explanation:

We are given;

- K is the midpoint of JL

- M is the midpoint of LN

By definition of mid points, we can say that;

JK = KL and LM = MN

Now, we are given that JK = MN.

Thus, by substitution, we can deduce that; KL = LM

Thus is because JK can be replaced with KL and MN can be replaced with LM.

Thus, it is proved that KL = LM
