its a quadratic equation with one variable
Answer:
∠M=85 the shortest side is segment LM
Step-by-step explanation:
To figure out ∠m you need to add all of the angles together and make them equal 180.
(2x+5)+(3x+10)+(x+15)=180 Set the angles up to 180
6x+30=180 Combind like terms
6x=150 Subtract 30 from both sides
x=25 Divide by 6
Now you take x and plug it into ∠M
3x+10 The equation for angle M
3(25)+10 Add x into the equation
75+10 Multiply 3 by 25
85 Add 10
85=∠M
This is angle M. Now you have to do this for the rest of the of the angles.
2x+5 The equation for angle L
2(25)+ 5 Add x into the equation
50+5 Multiply 2 by 25
55 Add 5
55=∠L
x+15 The equation for angle N
(25)+15 Add x into the equation
25+15 Add 15
40
40=∠N
15 % are 9 puppies
100% are x dogs
______________________
x = 9*1/0,15 = 60
There are 60 dogs in a shelter altogether.
Answer: 0.6 repeating
Step-by-step explanation:
Step-by-step explanation:
By the exterior angle theorem,
10x+36+7x=23x
17x+36=23x
36=6x
x=6
So measure of angle MAE is 23(6)=138 degrees
