Answer:
Width = 10 and Length = 16
Step-by-step explanation:
→ Assign variables to the length and width
width = x so length = 6 + x
→ Make an equation
x + 6 + x + x + 6 + x = 52
→ Simplify
4x + 12 = 52
→ Minus 12 from both sides
4x = 40
→ Divide both sides by 10
x = 10
→ Resubstitute into the previously assigned values
width = 10 so length = 16
Using ur calculator you should get 15 degrees ( Use the sin-1 key.).
Angle complementary to x is 90-15 = 75 degrees
and as sin x = cos(90-x) then cos 75 is also equal 0.2588
Answer:
C
Step-by-step explanation:
it is true because al triangles angles MUST add up to 180
