Hello! So the first thing you want to do is fix the triangles so they are in the same rotation (you can tell which point goes where by matching the points of Trangle PQR to Triangle STU). Next, it’s a matter of addition and subtraction. You add the two known angle measures (46 and 70) and then subtract it from the total degrees a triangle has (180). You should then get 64 as your answer. Hope this helps :)

Answer:
Crops are genetically modified to allow higher yields due to the production of molecules that are toxic to insect pests, but have no effect on animals and humans. ... Crops that are resistant to herbicides can also provide higher yield as the farmer can reduce the number of competing weed species in the field.

Answer with step-by-step explanation:
If AD = DB, then D would be the midpoint of AB. If AB = BC, then B would be the midpoint of AC. If so, lets add another point called E. E is the midpoint of BC, which would divide AC into fourths. DC = DB + BE + EC. So, DC is 3/4 of 24, which is 18.
Hope this was helpful!

1. supplementary, 2x+130=180
2. adjacent, 4x+32=140
3. vertical, 10x+21=121
