This is what I found
Step-by-step explanation: <em>If you look at the figure, the angle marked red is equal to 70° because vertical angles are equal. So, that also means that the opposite angle 2 is also 70°. So, the first equation is:</em>
<em />
<em>70 = 5x + y</em>
<em />
<em>Next, the green angle as marked is equal to</em>
<em>Green angle = 180 - 70 = 110</em>
<em>Being vertical angles, angle 1 is then equal to 110°. So,the second equation is</em>
<em />
<em>110 = 5x + 3y</em>
<em />
<em>Subtract the two equations:</em>
<em />
<em> 5x + y = 70</em>
<em> - 5x + 3y = 110</em>
<em>________________</em>
<em> -3y = -40</em>
<em> y = -40/-3 = 13.33°</em>
<em />
<em>Substituting y to either one of the equations,</em>
<em>5x + 13.33 = 70</em>
<em>Solving for x,
</em>
<em>x = 11.33°</em>

Answer:
- equation: 10(-270 +n) = -20
- number: 268
Step-by-step explanation:
If n represents the number, we have ...
10(-270 +n) = -20 . . . an equation for n
__
The solution can be found as ...
-270 +n = -2 . . . . . divide by 10
n = 268 . . . . . . . add 270
The number is 268.
Answer:
Country A = 85, Country B = 29, Country C = 20
Step-by-step explanation:
A+B+C=134 ----- eq(1)
B=C+9 ------------ eq(2)
A=36+B+C ------ eq(3)
By substituting eq(2) in eq(3), we get:
A=36+C+9+C
A=2C+45 ------- eq(4)
Now substituting eq(2) & eq(4) in eq(1), we get
2C+45+C+9+C=134
4C+54=134
4C=134-54
4C=80
C=20
Now putting the value of C in eq(2),
B=20+9
B=29
Substituting the value of B & C in eq(1), we get:
A+29+20=134
A+49=134
A=134-49
A=85
