Answer:
x = 15
Step-by-step explanation:
9x - 5 = 7x + 25 ......(vertical angle and corresponding angle )
9x - 7x = 25 + 5
2x = 30
x = 30 / 2
x = 15
W can be represented in the following equation: 14/tan 38°=w
Since tan 38 equals 0.78128563, we divide 14 by 0.78128563 which gives a value of 17.91
W= 17.91
W+X (which is the whole lenght) can be represented in the equation: w+x=14/tan 19°
So
17.9+X=14/0.34432761
we isolate for x and obtain
X= 40.65-17.9
X=22.75 (which we round to 22.8)
So the answer is option 4:
w = 17.9; x = 22.8
Answer:
X=-3
Step-by-step explanation:
To find the unknown variable: X, we need to see how mich 4x equals to. to do this, we must first subtract 3 from both sides of the equation. The left side will be left with -12, and the right side will be left with 4x. This means:
-12=4x So...
x=-3
To check if this is right, you can subsitute this back into the equation.
4 times -3= -12. -12=3=-9
