Can someone explain this to me? ​

Mathematics
1 answer:
Brilliant_brown [7]3 years ago

Answer:

y=42 degrees.

Step-by-step explanation:

The sum of angles in a triangle = 180 degrees.

One angle in that small triangle is y, one is 48, and one is unknown.

The sum of angles on one line is 180 degrees.

One of the angles on the line that unknown angle lies on is 90 degrees, so the unknown angle is 90 degrees, too.

90 + 48 = 138

180 - 138 = 42.

What is the converse of the linear pairs theorem
marysya [2.9K]
The converse of a logicalstatement is a s tatement formed by reversing the parts of the statement.

For example, the logical statement "A implies B" has a converse of "B implies A"

The linear pairs theorem states that "<span>if two angles form a linear pair, then they are supplementary".</span>

The converse of the linear pairs theorem is therefore, "if two angles are suplementary, then they form a linear pair".

3+ jk + k*3 when j=2 and k=6
Licemer1 [7]
The answer is 39, jk=18 because j multiplied by k is 18 and then i added 3 and i got 21, then k (6) multiplied by 3 is 18, so then i added 21 and 18 and i got 39

In a naval engagement, one-third of the fleet was captured, one-sixth was sunk, and two ships were destroyed by fire. One-sevent
Otrada [13]

Answer:

60 ships.

Step-by-step explanation:

Let the total number of ships in the naval fleet be represented by x

One-third of the fleet was captured = 1/3x

One-sixth was sunk = 1/6x

Two ships were destroyed by fire = 2

Let surviving ships be represented by y

One-seventh of the surviving ships were lost in a storm after the battle = 1/7y

Finally, the twenty-four remaining ships sailed home

The 24 remaining ships that sailed home =

y - 1/7y = 6/7y of the surviving fleet sailed home.

Hence

24 = 6/7y

24 = 6y/7

24 × 7/ 6

y = 168/6

y = 28

Therefore, total number of ships that survived is 28.

Surviving ships lost in the storm = 1/7y = 1/7 × 28 = 4

Total number of ships in the fleet(x) =

x = 1/3x + 1/6x + 2 + 28

Collect like terms

x - (1/3x + 1/6x) = 30

x - (1/2x) = 30

1/2x = 30

x = 30 ÷ 1/2

x = 30 × 2

x = 60

Therefore, ships that were in the fleet before the engagement were 60 ships.

BRAINLIEST TO CORRECT HURRY
dlinn [17]

Answer:

-5 5/10, -32/40,5

whenever a number has a negative sign,the larger the number the smaller.

i.e (-55/10= -5.5) is smaller than -32/40=-0.8 and then the greatest is 5 since it is a positive number and positive numbers are greater than negative numbers.
