Answer:
180
Step-by-step explanation:
Each triangle shown is a right triangle, meaning the angle is 90 degrees. All triangles equal 360 degrees, and you already have 2 90 degree angles, so just subtract 180 from 360 and you get 180.
1.
1=87 corresponding angle.
2=180-87=93
2.
1=78 corresponding angles
2=78 verticle angles
3.
Set it up as (6x - 11) = 37
37 + 11 =48
6x = 48
x = 8
4.
Take 142 and see that it is supplementary to angle 2 so 180-142 = 38
38 is corresponding to the equation 2(x + 9)
So 2(x + 9) =38
Distributive property
2x + 18 = 38
38-18=20
2x =20
x = 10
Angle 2 is equal to 38 from supplementary to 142
I’m pretty positive about 1-3 but 4 maybe not be correct. But most likely these are correct
Use distance formula:
d = √( (x₁ - x₂)² + (y₁ - y₂)² )
Here you have x₁ = 5, x₂ = 2, y₁ = 5, y₂ = 9
So that would be √( (5-2)² + (5-9)² ) = √( (3)² + (-4)² ) = √(9+16) = √25 = 5
Final answer: 5 units
