Answer:
Step-by-step explanation:
2x+5= -25 .........(1)
and -3m-6= 40........(2)
Considering (1): 2x+5= -25
2x = -25 - 5
2x = -30
x = -30/2
x = -15
Considering (2): -3m-6= 40
-3m = 40 + 6
-3m = 46
m = -46/3
Product of x and m = (-15) × (-46/3)
= -5 × -46
= 230
10.5 hope it helps I just did it in my head lol

since all interior angles in a triangle must be 180°, that means that C = 180 - 75 - 34.6 = 70.4. Let's find AD, which is the other sides pair length.
now, check the picture below, let's find the altitude of the parallelogram.
