WILL MARK BRAINLIEST

Mathematics
1 answer:
Troyanec [42]3 years ago
7 0

Answer:

Lengths all the three sides are 9m, 18m and 12m

Step-by-step explanation:

Let us assume the length of the second side  to be x m

According to the question:

first side = 2x

third side = x + 3

Applying the formula of perimeter:

Perimeter = length + breadth + height

39 = 2x + x + (x + 3)

39 = 2x + x + x + 3

39 = 4x + 3

39 - 3 = 4x

4x = 36

x = \frac{36}{4}

x = 9

length of the first side (x) = 9 m

length of the second side (2x) =2 × 9 =18 m

length of the third side (x + 3) = 9 + 3 = 12 m

∴ lengths all the three sides are 9m, 18m and 12m

What is two more than 4 times a number is -18 translated and solved
Brrunno [24]

Answer:

n=-5

Step-by-step explanation:

Let "n" represent the unknown number.

So, the equation asks for 4n and two more, or +2, that is all equal to -18.

So, your equation will be:

4n+2=-18

First, subtract 2 from both sides:

4n+2-2=-18-2\\4n=-20

Then, divide both sides by 4:

\frac{4n}{4}=\frac{-20}{4}\\n=-5

Therefore, n=-5.

HI CAN SOMEONE PLZ HELP ME I HAVE NO CLUE HOW TO DO THIS SOS. THANKS SM!!!❤️❤️❤️
Kitty [74]

Problem 1)

This question is incomplete. It asks us to find something, but doesn't say what to find. It's literally blank after the word "find" which suggests your teacher made a typo. Please get back to me on this. Thanks.

===================================

Problem 2)

Angles GAR and GAT are supplementary because they are a linear pair. They form a straight angle. So we add up the expressions of x for each of these angles, solve for x, and use this to find angle GAR.

(angle GAR) + (angle GAT) = 180

(5x) + (3x+4) = 180

8x+4 = 180

8x+4-4 = 180-4

8x = 176

8x/8 = 176/8

x = 22

Note: now that I reached this point I realize that this might be the answer to problem 1; however, I'm not 100% sure because of the incomplete problem.

Use this x value to find angle GAR

angle GAR = 5*x

angle GAR = 5*22

angle GAR = 110

Unfortunately this answer isn't listed. I'm thinking your teacher made another typo.

===================================

Problem 3)

Answer: angle GAR and angle ABQ are corresponding angles.

Thankfully this answer is listed. Corresponding angles are angles that are on the same side of the transversal line and they are either both above or below the parallel lines they are next to. In this case, they are both above the parallel line counerparts.

===================================

Problem 4)

Corresponding angles are congruent as long as we have a set of parallel lines. So that means angle ABQ is equal to angle GAR. So angle ABQ is also 110 degrees

===================================

Problem 5)

angle BAT = angle GAR,  because they are vertical angles

angle BAT = 110

angle BAT = (angle BAD) + (angle DAT)

(angle BAD) + (angle DAT) = angle BAT

(100) + (angle DAT) = 110

angle DAT = 110-100

angle DAT = 10

angle ADB = angle DAT,  because they are alternate interior angles

angle ADB = 10

--------

Final Answer: 10 degrees
