Answer:
v=10
Step-by-step explanation:
these 2 angles add up to 90 degrees bc of the right angle marker
6v-3 + 4v-7 = 90
combine like terms: 6v+4v and -3+-7
10v -10 = 90
isolate the variable by first adding 10 on both sides to get:
10v = 100
then divide 10 on both sides to get v
v=10
u can plug in the values to make sure it's right:
4(10)-7=33
6(10)-3=57
33+57=90
