Answer:
Point Slope: y - 5 = 3 (x-2)
Slope Intercept : y=3x-1
Step-by-step explanation:
1.) y - 5= 3(x-2)
2.) y - 5 = 3x-6
3.) y=3x-1
Answer:
1) x = 60° ; y = 70°
2) x = 50° ; y = 80°
3) x =110° ; y = 60°
4) x =60° ; y = 90°
Step-by-step explanation:
1)
We have to find the interior angle y
= 180 - 120
= 60°
Now we have to find x
=180 - (60 + 50)
= 180 - 110
= 70°
2)
We know that opposite angles are equal
So therfore y = 80°
x = 180 - 80 + 50
x = 180 - 130
x = 50°
3)
According to the figure we see that x+y=180
Exterior angle = sum of two interior angle
So, x = 50 + 60
x = 110°
Now we substitute in the x value
x + y = 180
110 + y = 180
y = 180 - 110
y = 70°
4)
Opposite angles are equal
x = 60°
The figure is a right angle triangle
So,
y =90°
9/10 = z/8
cross multiply
9/10(10)(8) = z/8(8)(10)
9(8) = z(10)
72 = 10z
Isolate the z, divide 10 from both sides
72/10 = 10z/10
z = 72/10
z = 7.2
7.2, or D) is your answer
