Triangle= 180 degrees
Angle = 37.5 degrees
Supplement angle = 105 degrees
If you multiply the angle (37.5) by 2 and then add 30, it gives you 105. Then add 37.5 twice to make up the other two angles of the triangle and it gives you 180 total degrees as a triangle should.
Answer:
k ≥ 12
Explanation:
We are given that the least possible value for k is 12.
This means that k can either be 12 or more.
Translating this into an inequality, we will find that the inequality is as follows:
k ≥ 12
Hope this helps :)

Answer:
Blank 1: 50
Blank 2: 95
Blank 3: is not
Blank 4: is not
Step-by-step explanation:
A right angle is 90 degrees, and a rectangle is a plane figure that has four straight sides and four right angles.
There is a formula for this
Time = [Worker 1 * Worker 2] / [Worker 1 + Worker 2]
Time = 30*40 / (30+40)
Time = 1,200 / 70
Time =

Alternate method
In 1 minute, Mark can clean (1/30) of a room
In 1 minute, Lynn can clean (1/40) of a room
Together, they can clean (1/30 + 1/40) = (7 / 120) of a room in 1 minute.
Together, they can clean one room in (120 / 7) minutes.
(120 / 7) =
