Answer:
7 or 
Step-by-step explanation:
Each triangle has the surface area of 1.5, because 1 
3 = 3 / 2 = 1.5. You divide by two because it is half a rectangle instead of a full one. You multiply by four which would get you 1.5 4 = 6. The square in the middle has the surface area of 1 because 1 1 = 1. So you would get 7.
I believe you do 180 - 149 because it's a linear pair, it makes a t shape!!
8,350 lb.
1 ton = 2000 lbs, 2000 x 4 = 8000 + 350 lbs = 8,350 lbs
Answer:
∠ XYZ ≈ 72.9°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tanXYZ = 
= 
= 
, thus
XYZ = 
( ) ≈ 72.9° to 1 dec. place )
Answer:
x = 25
Step-by-step explanation:
Given
4x + 50 = 150 ( subtract 50 from both sides )
4x = 100 ( divide both sides by 4 )
x = 25
