Gas is $2.53⁹ per gallon today, at that filling station
down the street from my house.
I have $10 in my pocket.

a). How much gas can I put in the car if I go there ?

b). My car gets 25 miles per gallon.  How many 'miles' will my $10 buy ?

c). In Calgary (Alberta, Canada) today, gas is selling for
89¢ (Canadian) per liter.  What is the percentage more or less,
compared to the price of gas down the street from my house ?

If I posted this problem on Brainly, I'd probably give it
something like 5 points for part-a, another 5 for part-b,
and 10 or 15 for part-c because in addition to math,
that part takes some research.

Find the value of x. Give reasons to justify your solution-
weqwewe [10]

Answer:

x =27

Step-by-step explanation:

from Z angls rule  the agle (BDE) =72

and total angl on D =180

so, 2x +2x+72=180

4x = 180 -72

4x = 108 (divied both sides by 4)

x= 27

Lines AC←→ and DB←→ intersect at point W. Also, m∠DWC=138° .
mr_godi [17]

m∠DWC=138°, ∠AWB = 138°, ∠AWD = 42°, ∠BWC = 42°

Solution:

Line \overrightarrow{A C} \text { and } \overrightarrow{B D} intersect at a point W.

Given m \angle D W C=138^{\circ}.

<em>Vertical angle theorem:</em>

<em>If two lines intersect at a point then vertically opposite angles are congruent.</em>

<u>To find the measure of all the angles:</u>

∠AWB and ∠DWC are vertically opposite angles.

Therefore, ∠AWB = ∠DWC

⇒ ∠AWB = 138°

Sum of all the angles in a straight line = 180°

⇒ ∠AWD + ∠DWC = 180°

⇒ ∠AWD + 138° = 180°

⇒ ∠AWD = 180° – 138°

⇒ ∠AWD = 42°

Since ∠AWD and ∠BWC are vertically opposite angles.

Therefore, ∠AWD = ∠BWC

⇒ ∠BWC = 42°

Hence the measure of the angles are

m∠DWC=138°, ∠AWB = 138°, ∠AWD = 42°, ∠BWC = 42°.
