Answer:
y = 50 x = 10.
Step-by-step explanation:
Let's solve for y first.
We know the line angle 80 and angle 2y-5 is on a 180 degree line.
Now we can do our work:
180 - 85 = 95
2y - 5 = 95
95 + 5 = 100
100 ÷ 2 = 50
2(50) - 5 = 95?
The equation is correct, therefore y = 50.
No we do the same thing for the other angles, 90 and 3x + 55.
Again, 180 line.
180 - 95 = 85
3x + 55 = 85
85 - 55 = 30
30 ÷ 3 = 10
3(10) + 55 = 85?
The equation is correct therefore x = 10.
Thus, y = 50 and x = 10.
Answer:
-5x - 2
Step-by-step explanation:
Answer:
x = -5
Step-by-step explanation:
- Subtract 3 from each side, so it now looks like this: 2x = -10
- Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = -5
I hope this helps!
Answer:
Step-by-step explanation:
ΔVWX is an isosceles triangle.
∠V ≅∠W = 20
20 + 20 + ∠X = 180
∠X = 180 - 40
∠x = 140
In ΔPQR
∠P + 20 + 80 = 180 {Angle sum property of triangle}
∠P + 100 = 180
∠P = 180 - 100
∠P = 80
In ΔSTV is an isosceles triangle.
∠S ≅ ∠T = 80°
∠V + 80 + 80 = 180
∠V + 160 = 180
∠V = 180 - 160
∠V = 20°
In ΔPRQ & ΔSTV
∠P ≅ ∠S = 80°
∠R ≅ ∠T = 80°
∠Q ≅ ∠v = 20°
ΔPRQ ` ΔSTV are similar by AAA congruent
Answer:
Since magnesium = 2, and potassium = 1, magnesium is greater than potassium (2 > 1).
If we assign these elements letters, m and p respectively,
