Answer: The slope of DE is 0.5 and the length of DE is 1.6 units.
Explanation: Given that the midpoints D and E of triangle ABC are joined by line segment DE, this line segment DE will be parallel to BC and will measure half of the length of BC according to the midpoint theorem for triangles. Therefore, the slope of DE is
slope of DE = slope of BC = 0.5
since they are parallel, and the length of DE is
length of DE = 0.5 * length of BC = 0.5 * 3.2 = 1.6 units.

Answer:
5 units
Step-by-step explanation:
If point T is on the line segment SU, then ST + TU = SU.
Given
TU = 4x + 1
SU = 8
ST = 3x
To get TU, we need to get the value of x first. To get x, we will substitute the given parameters into the formula;
3x+4x+1 = 8
7x+1 = 8
subtract 1 from both sides
7x+1-1 = 8-1
7x = 7
divide both sides by 7
7x/7 = 7/7
x = 1
Substitute x = 1 into the length TU
Since TU = 4x+1
TU = 4(1)+1
TU = 5
Hence the numerical length of TU is 5 units
the 3 angles of a triangle need to equal 180 degrees
50 +70 = 120
180 - 120 = 80
the 3rd angle = 80 degrees
