X+16=3
move +16 to the other side
sign changes from +16 to -16
X+16-16=3-16
X=-13
answer:
X=-13
When we have a right triangle with sides and angles, we use basic trigononemetry. Since we know the vertical leg (height of ramp) and horizontal leg (base length of ramp), we use the inverse tangent function to find the angle.
θ = tan-1(height of ramp / base of ramp) θ = tan-1(2.5 / 6) θ = tan-1(5 / 12)
Answer:
<h2>The answer is x = y = 10.</h2>
Step-by-step explanation:
It is given that,
.
Another equation is given by,
.
Putting the value x = 2y - 10, in the second equation, we get
.
![x = 2y - 10 = 20 - 10 = 10](https://tex.z-dn.net/?f=x%20%3D%202y%20-%2010%20%3D%2020%20-%2010%20%3D%2010)
Answer:
Step-by-step explanation:
8x - 2y = 6
-8x + 4y = 12
2y = 18
y = 9
8x - 18 = 6
8x = 24
x = 3
(9, 3)
100/30=3.3*
9x3.3*=30
T=30 metres
