Full question:
A car's speed is 80 km/h. How far does it travel in a minute?
Answer and explanation:
1 hour = 60 minutes
Therefore if a car travels 80km in one hour, in one minute it would travel
80km/ 60 minutes = 1.333km
Therefore a car that travel 80km per hour would travel 1.333km per minute

Answer:
assume both unknown angles as x so x+x=2x
then 180° (2x+90)=90/2
angle x =45°
another angle = 180-[90°+45°]
. 180°-135°
=45°
so angle x =45°
another angle = 45°
Answer:
B
Step-by-step explanation:
it's basically 2+7
Answer:
K = 10
Step-by-step explanation:
Interior angle adjacent to y = 180-115 = 65
Sum of interior angles in a triangle = 180
This the remaining interior angles for the triangle = 180-65= 115
In other words,
4K+5+6k+10 = 115
Simplify and solve:
10k + 15 = 115
10k = 115-15=100
K= 100/10 = 10
Hope this helps.
Good Luck
