Answer:
m∠3 = 119°
Step-by-step explanation:
All the angles must equal 360° when added together. You have two known angles that are right next to each other. If you add m∠1 and m∠2, 119 + 61, it is equal to 180°. This means that m∠3 and m∠4 must be equal to 180° as well and since there are only two lines, it is safe to assume that opposing angles are the same so m∠1 = m∠3 and m∠2 = m∠4.
Answer:
(15m^2 + 5)
Step-by-step explanation:
(m2 - 3m + 19 ) + (2m2 + m) + (4m2 - 7) + (2m2 + m) + (4m2 - 7) + (2m2 + m)
15m2 + 0m + 5
=> <u>15m^2 + 5</u>
25 and 60 as the parallel lines means they have wth same gradient
Triangle area = (1/2) base * height
60 = 3.5 * base
base = 60 / 3.5
base =

The domain is all of the x values in a set and the range is all of the y-values in a set.
If you have a bunch of points such as (3,6), (7,2), (1,5) the domain would be stated as D={3, 7, 1} and the range would be stated as R={6,2,5} If you have a line, then the domain and range would be set up differently. For example, if you have a line with end points at (-3,2) and (5,8) then the domain would be D=(-3,5) and the range would be R=(2,8)
