Answer:
-2/45
Step-by-step explanation:
-3/5 - (-5/9)
Subtracting a negative is like adding
-3/5 + 5/9
Get a common denominator of 45
-3/5*9/9 + 5/9 *5/5
-27/45 + 25/45
-2/45
Tan67=h/137
h=137tan67
h≈322.751 ft
h≈322.75 ft (to nearest hundredth of a foot)
Answer:
5√10
Step-by-step explanation:
The distance between two points A(
) and B(
) on the coordinate plane is given by:

From the image attached the coordinates of the points are E(-1, -1), F(8, -4), C(-7, -4) and D(-1, 2).
Hence the lengths of the line segment EF and CD are:

Answer:
1.187991
Step-by-step explanation:
sin^2(225)−(cos(330))(cos(240))
=(−0.930095)2−(cos(330))(cos(240))
=0.865076−(cos(330))(cos(240))
=0.865076−−0.991199(cos(240))
=0.865076−(−0.991199)(0.325781)
=0.865076−(−0.322914)
=1.187991
