Answer: D. 4
Step-by-step explanation:
In the given picture , we have given a triangle ΔMLN in which
ML= 4x and MN= x+3
∠L=∠N=50°
⇒ MN=ML [∵ Basically by Isosceles triangle property :sides opposite to equal angles of a triangle area equal.]
Subtract x from both sides , we get
Divide bothe sides by x , we get
1= x or x =1
Then, the length of MN = x+3=1+3=4 units
Answer:
37.5 degrees
Step-by-step explanation:
Congruent angles are the ones that are the same in value, in the attached image we can see the atom, the O atom forms 105 with both H atoms, if we use trigonometry we have
x+x+105=180
x=37.5 degrees the angle
Answer:
y = -3 m = -1 b = 3
Step-by-step explanation:
-3y=3x-9
To isolate the y variable, divide both sides by -3.
y = -1x + 3
y = -3
m = -1
b = 3
