Question

If the measures of two sides and the included angle of a triangle are 7, √50
and 135° respectively then the measure of the line segment joining the mid
points of the two given sides is.
30​

Answer 1

Answer:

6.04

Step-by-step explanation:

I am considering the first line to lie along the x axis 7i

midpoint = 3.5i

Therefore the second line is √50 of length and 135 from the first one, therefore it lies in the second quadrant

components √50(-cos45i + sin45j)  = -5i + 5j

midpoint =  -2.5i +2.5j

Length of line joining the mid points= √(5.5)²+(2.5)²

                                                             =6.04
