Answer:
For angle B which is 50 degrees,
hypotenuse = AB =?
Adjacent = BC = 2 units......(given)
cos 50 = adjacent / hypotenuse
0.643 = 2 / AB. .....(as cos 50 = 0.643 approx)
AB * 0.643 = 2
AB = 2 / 0.643
AB = 3.11 units(approx)
Answer equal to 3 because 3+4 =8-5 equal 3
Answer:
(-5, -3)
Step-by-step explanation:
Scale factor 1/2 means divide points by 2
First, 0.0004853 is < 1, so we need to multiply the number by 10 to a negative power if it's greater than 1 (if that makes sense i cant describe it better)
So, b and c is incorrect.
10 to the power of negative 4 = 0.0001, and 4.853 x 0.0001 = 0.0004853 (true), so answer is a
x > -3 divide by -5 on both sides and then switch the sign bc everytime u divide by a negative number u have to switch the sign
