Hey there!!
In the figure, we have two angles. And the sum of these both angles is mentioned as 134°.
Angle ABC is (4x-1)° and Angle CBD is (6x+5)°
Angle ABC + Angle CBD = 134°
... 4x - 1 + 6x + 5 = 134
... 10x + 4 = 134
... 10x = 134-4
... 10x = 130
... x = 130 ÷ 10
... x = 13
Now, we will have to find the angle ABC and the angle ABC is given as 4x-1.
Hence, angle A =
... 4(13)-1
... 52-1
... 51.
<em>Hence, the required answer is 51°.</em>
Hope my answer helps!
S=d/t ⇒d=s*t
s=speed
d=distance
t=time
The first train :
d=x
x=70 miles/h*t ⇒ x=70t (1)
The second train
d=360 miles - x
360 miles - x=80 miles/h*t ⇒360-x=80t ⇒ x=360-80t (2)
therefore, with the equations (1) and (2) we have a systeme of equations:
x=70t
x=360-80t
we can solve this system of equations by equalization method.
70t=360-80t
70t+80t=360
150t=360
t=360/150=2.4 (≈2 hour 24 minutes)
Answer: the first train meet with the second train in 2 hour 24 minutes.
Answer:
I really don't know this one but I have a feeling it os option c
A = ( 15 , 15 )
B = ( 6 , 33 )
Thanks for watching buddy good luck.
