Answer:
110°
Step-by-step explanation:
All the angles add to 360.
Y+W = 180
and V+X = 180
to find W,
W = 180 - Y
W = 180-70
= 110
Because supplementary angles means mA + mB = 180.
Then subtract 80 from 180 which will get you 100.
So B = 100
Answer:
y =
x - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = -
x - 3 ← is in slope- intercept form
with slope m = - 
Parallel lines have equal slopes , then
y = -
x + c ← is the partial equation of line d
to find c substitute (- 2, - 2 ) into the partial equation
- 2 =
+ c ⇒ c = - 2 -
= - 
y = -
x -
← equation of line d

150mm is the same as 15cm
15cm:60cm
both divisible by 15
1cm:4cm

Factorize the numerator and denominator, then simplify:
10/45 = (2×5)/(9×5) = 2/9
Now,
1/9 = 1/10 + 1/90
1/90 = 1/10 × 1/9 = 1/10 × (1/10 + 1/90) = 1/100 + 1/900
1/900 = 1/100 × 1/9 = 1/100 × (1/10 + 1/90) = 1/1000 + 1/9000
and so on, which is to say
1/9 = 1/10 + 1/100 + 1/1000 + …
or
1/9 = 0.111…
so that multiplying both sides by 2 gives
2/9 = 0.222…
