Answer:
A -60i - 14j
Step-by-step explanation:
u = -9i + 8j
v = 7i + 5j
2u = 2(-9i + 8j) = -18i + 16j
6v = 6(7i + 5j) = 42i + 30j
2u - 6v
(-18i + 16j) - (42i + 30j)
(-18i - 42i) + (16j-30j)
-60i - 14j
Answer:
120 degrees the sum of all angle is 720 degrees In the above
i think it would be 2 degrees every hour for 10 to 11 hours i think it would be 2 degrees
Answer:
B
Step-by-step explanation:
Angles a and b are complementary angles because they both add up to 90 degrees, which fulfills the definition of complementary.
48 - 3 = 45.
45 divided by 6 = 7.5
That means that the width is 7.5 and the length is 18. Hope it helps! :)
