Answer:
x = 3
Step-by-step explanation:
Given the 2 equations
- 2x + y = 5 → (1)
- 5x + y = - 4 → (2)
Multiply (2) by - 1 then add to (1) to eliminate y
5x - y = 4 → (3)
Add (1) and (3) term by term to eliminate y
3x = 9 ( divide both sides by 3 )
x = 3
Answer:
120°
Step-by-step explanation:
Recall:
The sum of interior angles if a parallelogram equals 360;
The sum of the angles can be defined as :
(x + 2x + x + 2x) = 360
6x = 360
x = 360/6
x = 60°
The angle BCD = 2x
Hence, angle BCD = 2(60°) = 120°

Answer:
C) 4tan34
Step-by-step explanation:
TOA
tan(x) = Opposite/Adjacent
Opposite the angle, adjacent meaning next to the angle
sub in values
tan(34) = x/4
multiply each side by 4
x = 4tan(34)
There's your answer.
