Answer:
2
Step-by-step explanation:
this is a 30-60-90 Δ and the ratio of the sides are 1 :
: 2
1 / 2 =
/ x
cross-multiply: x = 2
Answer:
x=35
Step-by-step explanation:
When a is parallel to b, the two angles will add to 180
x+ 3x+40=180
Combine like terms
4x+40 =180
Subtract 40 from each side
4x= 180-40
4x= 140
Divide by 4
4x/4 = 140/4
x=35
Example C: w cubed z, +, 5, z squared, minus z squared, +, 6 ..... For example, 2x + 1 = 7x and 10x minus 9y minus z = 3 are linear equations, but x, +, y ...
