Answer:
point m is -5;7 but point l is 9;12
Step-by-step explanation:
m there is negative but l is positive
Answer:
θ = 27.47°
Step-by-step explanation:
This problem can be represented as a right-angled triangle, as shown in the diagram below.
To find θ, we apply the tangent part of the trigonometric ratios SOHCAHTOA:
tanθ = 
In the diagram, opposite = 1.3 m and adjacent = 2.5 m
Hence:
tanθ = 
tanθ = 0.52
θ = 
θ = 27.47°
The ramp forms 27.47° with the ground.
2/3 = x/(3x + y)
Cross multiply:
3x = 2(3x + y)
Distribute 2:
3x = 6x + 2y
Subtract 6x to both sides:
-3x = 2y
Divide 'y' to both sides:
-3x/y = 2
Divide -3 to both sides:
x/y = -2/3
Answer:
Step-by-step explanation:
2+4(6-2x)=8
2+24-8x=8
26-8x=8
26-8=8x
18/8=x
2.25=x
substitute the value of x
2+4(6-2x)
2+4(6-2*2.25)
2+6
8
therefore 8=8 so it is true
