You have to build an equation to find the answer,
angles in a straight line add upto 180°
so your equation would be,
12x+30°=180°
-30 -30
=12x=150°
÷12 ÷12
=x=12.5°
now find the measures of the angles by using 12.5 as x.
angle EAF= 2x
=2×12.5
=25° degrees
angle DAE= 4x
=4×12.5
=50°degrees
angle CAD=6x
=6×12.5
=75°degrees
check,
30+25+50+75=180°degrees
hope this helps.......
Answer:
D. The scuba diver was 35 meters below the surface of water at the start of the ascent.
Step-by-step explanation:
The y-intercept of the graph representing the scuba's driver ascent to the surface is -35.
This represents the starting level below the surface of the water.
✅-35, means that the driver was 35 meters below the surface of water at the start of the scuba's ascent to the surface.
Answer:
Step-by-step explanation:
The satellite has 30 modular units.
There are equal numbers of non-upgraded sensors in each unit.
Let us assume that on the entire satellite there are x numbers of upgraded sensors.
Then as per the given condition, there are 
number of non-upgraded sensors in one unit.
Therefore, the number of non-upgraded sensors on the entire satellite is 
=6x
Hence, total number of sensors in the satellite is (x+ 6x) =7x
Therefore, the required fraction of the upgraded sensors is 
. (Answer)
Answer:
you don't have -i? because it should be -i
Answer:
common difference(d) = 11
first term (a)=11
then the nth term
=a+(n-1)d
=11+ (n-1)*11
=11+11n-11
=11n
