It’s 20 degrees because all triangles are all equal up to 180° and so if you add 135° to 25° you get 160° and so minus 160 from 180 and you’ll get 20°
Maybe The 30% And 70% Is In The Other Triangle And You Do The Same Thing Thats What I Am Guessing Not 100% Sure About It Because I Have Not Learned This Yet! :P
Ann should buy 14 yards of fabric to make the quilt because
1 yard = 3 feet
So to find how many yards are in 42 feet yo divide 42 by 3 and you get 14 yards
Speed = distance / time
Speed = 200 meters / 20 seconds
Speed = 10 meters / second
1 meter per second = 3.6 km per hour
10 meters per second x 3.6 = 36 km per hour
