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)
Switch the y and x then solve for y, so I believe b.
True, because all angles on a straight line add up to 180 deg

Answer:10
Step-by-step explanation:
X/5+4 = 6
(Subtract 4 on both sides)
X/5 =2
(Multiply 5 on both sides to get x alone)
2(5) = 10
X = 10
