Answer:

Step-by-step explanation:

3h + 18 + 15h = 180 ( adjacent angles add up to 180 degrees).

`18h = 180 - 18 = 162

h = 162 / 18 = 9 (answer)

Answer: h=9
3h° + 18° + 15h°=180°
18h+18=180
18h=180-18
18h=162°
h=162°/18
h=9

What is the length of BD?

Ket [755]

Answer: BD = 9 units

Step-by-step explanation:

ABQ and CDQ are congruent triangles. That means their angle measures are the same but their lengths may be proportional.

19.2 / 32 = 0.6

15 * 0.6 = 9

So the length of side BD is 9 units.
