Answer:
x°=60°
y°=60
Step-by-step explanation:
For triangle abd it is ab equilateral triangle which means that all sides are equal.
Total angle in a triangle =180
x+x+x= 180
3x=180
x=60°
For troangle bcd it is an isosceles triangle which means only twi sides are equal
Answer:
1
Step-by-step explanation:
1/4 - ( - 3/4)
<em>{Multiplying two negative signs gives us positive sign}</em>
1/4 + 3/4
Add both of them:
1/4 + 3/4 = <u>1</u>

1.494 billion km from Saturn to earth, divided by 28,000
The chances of getting a g is 1/10
![m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{5 - (-1)}{-1 - 3} = \frac{5 + 1}{-4} = \frac{6}{-4} = \frac{3}{-2} = -1\frac{1}{2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_%7B2%7D%20-%20y_%7B1%7D%7D%7Bx_%7B2%7D%20-%20x_%7B1%7D%7D%20%3D%20%5Cfrac%7B5%20-%20%28-1%29%7D%7B-1%20-%203%7D%20%3D%20%5Cfrac%7B5%20%2B%201%7D%7B-4%7D%20%3D%20%5Cfrac%7B6%7D%7B-4%7D%20%3D%20%5Cfrac%7B3%7D%7B-2%7D%20%3D%20-1%5Cfrac%7B1%7D%7B2%7D)
y - y₁ = m(x - x₁)
y - (-1) = -1¹/₂(x - 3)
y + 1 = -1¹/₂(x) + 1¹/₂(3)
y + 1 = -1¹/₂x + 4¹/₂
- 1 - 1
y = -1¹/₂x + 3¹/₂
4x + y - 2 = 0
+ 2 + 2
4x + y = 2
4x - 4x + y = -4x + 2
y = -4x + 2
y - y₁ = m(x - x₁)
y - (-3) = -4(x - 4)
y + 3 = -4(x) + 4(4)
y + 3 = -4x + 16
- 3 - 3
y = -4x + 13
2x - 3y - 5 = 0
+ 5 + 5
2x - 2x - 3y = -2x + 5
-3y = -2x + 5
-3 -3
y = ²/₃x - 1²/₃
y - (-3) = -1¹/₂(x - 4)
y + 3 = -1¹/₂(x) + 1¹/₂(4)
y + 3 = -1¹/₂x + 6
- 3 - 3
y = -1¹/₂x + 3
