Can I get some help with this? Thanks​
iris [78.8K]

Step-by-step explanation:

first you need to know that angle 4 and angle d are the same measurement. so then you have to notice that a straight line is equal to 180 degrees. by knowing this you can make this equation

x+30+ 2x +15= 180

next combine like terms:

3x+ 45=180

next subtract 45 from both sides

3x=135

next divide by 3 on both sides to get x alone. this will give you your answer.

x=45

once you know this plug 45 into you equation to do d the value of the angle 4

Draw a modelto show that x + 3 is the same as x over 3​
Shalnov [3]

Answer:

Step-by-step explanation:

Your equation comes out to x + 3 = x/3.  Multiplying all three terms by 3 results in 3x + 9 = x, which simplifies to 2x = -9, so that x = -9/2.

Unsure of what you're asking for by "model."
