Answer:
median
Step-by-step explanation:
This can be solved using the
angle bisector theorem. Note that line segment AD is the angle bisector of triangle DAB from angle DAB. Therefore, we know that the ratios

and

are equal. Solving, we get

. Cross multiplying, we get

, and solving this equation we get

.
10.2 is your answer.
Answer:
x = 8
Step-by-step explanation:
∠VUD + ∠WUV = 180° {Straight line}
86 + ∠WUV = 180
∠WUV = 180 - 86
∠WUV = 94°
Sum of all angles of triangle = 180°
∠VUW + ∠UWV + ∠WVU = 180
94 + x + 8 + 9x - 2 = 180
10x + 100 = 180
10x = 180 - 100
10x = 80
x = 80/10
x = 8
Answer:
x=1
Step-by-step explanation:
Isolate the variable usually by dividing it by factors that don't contain the variable.
