Ican't find x or the measure of angle 13/14? i've tried everything

Angle 13 and 14 are equal to each other, we know this because they share a vertex like that, so you can set their equations equal to each other resulting in 2x+94=7x+49 and you can solve from there,
Subtract 2x from both sides and subtract 49 from both sides to get
45=5x then divide by 5 to get x=9 and then plug 9 into each equation to get
2(9)+94
And
7(8)+49
Totaling 18+94=112 and 63+49= 112

Good morning! i got on

If you are talking about typical sand you would find at the beach or in a river bed here on earth, there are some differences. i would say the first biggest difference is in composition and mineral make up. although the moon is largely made of the same materials as earth’s mantle and surface, the moon experiences very little weathering (no liquid water and virtually no atmosphere). “earth” sand is typically composed mostly of quartz grains. this is because quartz is highly resistant to both physical and chemical weathering. most of the other minerals originally with the quartz are broken down into fine clay and carried away, chemically eroded/ dissolved, or some combination of the two. this usually leaves only the quartz behind, and so most of the time when you see/think of sand, you are talking about quartz. without these weathering mechanisms on the moon, the “sand” (which is likely more silt or clay sized grains anyways) would consist of mostly other minerals like anorthosite, olivine, and proxene.
