Answer:
x = 15
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
3+6x + 5x+12 = 180
Combine like terms
11x+15 = 180
Subtract 15 from each side
11x+15-15 =180-15
11x = 165
Divide by 11
11x/11 =165/11
x =15
Answer:
-(√2) + √3
Step-by-step explanation:
2√3 - (√2 + √3)
2√3 - √2 - √3
2-1√3 - √2
√3 - (√2)
or.
-(√2) + √3

Answer:
Step-by-step explanation:
Given that x and y are proportional and the equation relating them is
y = rx ← r is the constant of proportionality
To find r use any ordered pair from the table
Using x = 9, y = 4.5 , then
4.5 = 9r ( divide both sides by 9 )
= r , that is
r =
Answer:
196
Step-by-step explanation:
find the slope with y2-y1 / x2-x1
points (7, 1372) and (12, 2352)
(2352- 1372) / 12-7
= 196

Answer:
Step-by-step explanation:
5²+10²=25+100=125
13²=169
so 5²+10²≠13²
so it is not a right angled triangle.
