Answer:
30
Step-by-step explanation:
10b/a
b = 6
a =2
10(6)/2
10x6 / 2 = 60/2
= 30

Answer: 130</h3>
Explanation:
Let x be the unknown angle we want to find.
Let y be adjacent and supplementary to x. This means x+y = 180
Let z also be adjacent and supplementary to x. So x+z = 180 also
Subtracting the two equations leads to y-z = 0 and y = z. So effectively we've proven the vertical angle theorem.
Since the supplementary angles to x add to 100, we know that y+z = 100. Plug in y = z and solve for z
y+z = 100
z+z = 100
2z = 100
z = 100/2
z = 50
Therefore,
x+z = 180
x+50 = 180
x = 180-50
x = 130

Step-by-step explanation:
Monday overall cost 36+5t
Tuesday overall cost 20+9t
36+5t=20+9t
-20 -20
16+5t =9t
-5t -5t
16=4t
t=4
Check
36+5t=20+9t (t=4)
36+20=20+36
It works
Answer:
21°
Step-by-step explanation:
GEW has angle measures given by m/_G=5x + 66, m?/_ E = 3x, and m/_ W= 142 -4x whats the mesure of e
= 5x + 66 + 3x + 142 - 4x = 180
4x + 208 = 180
4x = 208 - 180
4x = 28
x = 28/4
x = 7
Solving for E = 3x
E = 3 × 7
E = 21°
