X+x-24=180
2x-24=180
2x=204
x=102
x-24=the smaller angle
102-24=the smaller angle
78=the smaller angle
Hope this helps :)
Answer:
64°
Step-by-step explanation:
angle 1+40°=104°(sum of two non adjacent interior angles is equal to opposite exterior angle)
angle 1=104°-40°
angle 1=64°
3x-6+1=-2x-5+5x
3x+2x-5x=6-1-5
10x=0
x=0
Recall that using the pythaogorean theorem, which is only for right-triangles, the longest leg squared is the sum of the other two squared, namely c² = a² + b², now, if those units above are of a right triangle, then 25² = 7² + 24².
do they check out? if they do, then yes, you can make a right-triangle, if not, they nope.
Answer:
The time of a commercial airplane is 280 minutes
Step-by-step explanation:
Let
x -----> the speed of a commercial airplane
y ----> the speed of a jet plane
t -----> the time that a jet airplane takes from Vancouver to Regina
we know that
The speed is equal to divide the distance by the time
y=2x ----> equation A
<u><em>The speed of a commercial airplane is equal to</em></u>
x=1,730/(t+140) ----> equation B
<u><em>The speed of a jet airplane is equal to</em></u>
y=1,730/t -----> equation C
substitute equation B and equation C in equation A
1,730/t=2(1,730/(t+140))
Solve for t
1/t=(2/(t+140))
t+140=2t
2t-t=140
t=140 minutes
therefore
The time of a commercial airplane is
t+140=140+140=280 minutes
