The value of x in each figure is 34°, 17.1° and 75° respectively.
<h3>What is an
equation?</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
From the diagram:
1) x + 146° = 180° (sum of angles in a straight line)
x = 34°
2) x + 62.9° = 90° (complementary angles)
x = 17.1°
3) x + 105° = 180° (sum of angles in a straight line)
x = 75°
The value of x in each figure is 34°, 17.1° and 75° respectively.

To get the answer we have to use proportion
36% ------------------72
100% ----------------x
Crossmultiply now
100*72=36*x
7200=36x /:36 divide both sides by 36
7200:36=x
200=x - its the answer
Answer:
66
Step-by-step explanation:
Replace t with 9 in the equation.
Simplify.
Rounded, it equals 66
X = y x z
10 = (-4) x z
Z= -10/4 = -5/2
So now we know z = -5/2
we can find y when x = 2
Again x = y x z
<span>
2 = y x
(-5/2)</span>
<span>So y =2 x (
-2/5) = - 4/5</span>
Double check:
x = yx (x = 2 , y = -4/5), z = -5/2)
<span>
2 = (-4/5) x (-5/2) = 20/10 = 2
Answer: when x = 2, y = -4/5</span>
The answer is Y=3x-2. I used desmos.
