Someone pls help me with this.

Answer: m∠D = 65°

Step-by-step explanation:

The best solve method for problems like this is say the sum of the angle values equals 360.

2x-15+2x-15+x+x = 360

Then from here you just simplify.

4x+2x-30 = 360

6x = 390

x = 65

So the measure of Angle D equals 65 degrees.

skad [1K]

Answer:

$4$

Step-by-step explanation:

$4 - 0.25g + 0.5h = 4 - 0.25(10) + 0.5(5) = 4 - 2.5 + 2.5 = 1.5 + 2.5 = 4$

1 4/5 x 5/12 another question pls urgent<br>

gogolik [260]

Answer:

45/60 or 3/4

Step-by-step explanation:

You have to convert any mixed number into a fraction

1 4/5 = 9/5

5/12 = 5/12

Then you multiply across

9 x 5 = 45

5 x 12 =60

Then you would simplify the answer

What is the measure of the angle Z

QveST [7]

A straight line always = 360 degrees so subtract 43 from 180 and you get 137. So z is 137 degrees. Hope that helped!
