Answer:
x = 14
Step-by-step explanation:
Since they are similar triangles, their sides are proportional
12 : 15 :: 8 : x - 4
Product of extremes = Product of means
12 × ( x- 4 ) = 15 × 8
12x -48 = 120
12x = 120 + 48
12x = 168
x = 168/12
x = 14
Answer:
it would be 4/20 I thinkk
Step-by-step explanation:
Answer:
∠ABC = 50°
Step-by-step explanation:
Since this is a parallelogram, opposite angles are congruent.
Therefore, ∠D ≅ ∠B
∠D = 38° + 12°
∠B = 38° + 12°
∠B = 50°
∠ABC = 50°
Since that angle all together is 180, 100 is 2z-10 and z is 55
