M×10+m×13=138<br><br>sorry theres another loll I'm so bad at these
Dimas [21]
So first of all you would add the two together
so it would be m23.

138÷23 would equal 6,

therefore m would equal six

to check it substitute m for 6 and you should get 138!

Find the value of unknown angle x,y,z,a,b,c with reasons and full process​
Oduvanchick [21]

Answer:

Step-by-step explanation:

x = 70 degree (being vertically opposite angles)

y + 70 degree =180 degree (being linear pair)

y = 180 - 70

y = 110 degree

In triangle,

x + 60 + misssing angle = 180 degree (sum of interior angles of a triangle)

70 + 60 + missing angle =180

130 + missing angle = 180

missing angle = 180 - 130

missing angle = 50 degree

c = missing angle (being vertically opposite angles )

c = 50 degree

x + missing angle = a (sum of two interior opposite angles is equal to the exterior angle formed)

70 + 50 = a

120 degree = a

a = b (being vertically opposite angle

120 =b

therefore b is 120 degree

Hence , a = 120 degree , b = 120 degree , c = 50 degree , x = 70 degree , y = 110 degree

Help please ...........<br>number 13, 14, 15<br>​
AfilCa [17]

Answer:

13.  108 inches

14.  not similar (sides have different ratios)

15.  68

Step-by-step explanation:

13. You have two relationships between length and width:

  2L + 2W = 336 . . . . . the perimeter is 336 inches

  L/W = 9/5 . . . . . . . . . .the ratio of length to width is 9/5

Multiplying the second equation by 5/9W, we get

  5/9L = W

Now we can substitute that into the first equation to get ...

  2L +2(5/9L) = 336

Multiplying by 9 gives us ...

  18L +10L = 3024

And dividing by 28 gives ...

  3024/28 = L = 108 . . . . inches

___

14. Shortest to longest, the ratios of sides are 6 : 8 : 9 and 2 : 4 : 5. There is no value that will multiply the first ratio to give the second ratio. For example, multiplying by 1/3 gives ...

  2 : 2 2/3 : 3 . . . . <u>not</u> 2 : 4 : 5

Similar triangles have the same side ratios. These do not, so they are not similar triangles.

__

15. MP is a midsegment of triangle JKL and parallel to base JL. A midsegment is half the length of the parallel base. Then JL is twice as long as MP. JL is 68 units long.
