Answer:
a) 39 degrees
Step-by-step explanation:
angle REB + angle JEB = 180 degrees (because J, E, and R are collinear)
=> angle REB = 180 - angle JEB = 180 - 132 = 48 degrees
angle REB + angle ERB + angle RBE = 180 degrees (because the sum of 3 angles inside a triangle is 180 degrees)
=> angle RBE = 180 - angle REB - angle ERB = 180 - 48 - 93 = 39 degrees
Answer:
v = 99
Step-by-step explanation:
Given v varies directly as g then the equation relating them is
v = kg ← k is the constant of variation
To find k use the condition v = 36 when g = 4 , then
36 = 4k ( divide both sides by 4 )
9 = k
v = 9g ← equation of variation
When g = 11 , then
v = 9 × 11 = 99
Answer:
Age of Mark is 25 years.
Step-by-step explanation:
Let the current age of Mark = x years
After 20 years, age of Mark=(x+20) years
10 years ago,age of Mark was (x-10) years.
In 20 years Mark will be three times as old as he was 10 years ago.
