Answer:
x = 15
x = 15
The answers should be the same because the triangles are similar. The ratio of the sides are in the same proportion.
Step-by-step explanation:
a. x 12
------- = --------------
20 16
using cross products
x*16 = 20 * 12
16x = 240
divide by 16 on each side
16x/16 = 240/16
x = 15
b x 6
------- = --------------
20 8
using cross products
x * 8 = 6 * 20
8x = 120
divide each side by 8
8x/8 = 120/8
x = 15
c. The answers should be the same because the triangles are similar. The ratio of the sides are in the same proportion.
Answer:
x= 15 for parts A and B.
Step-by-step explanation:
x/20 is the same as 12/16 which after cross multiplying is 16x = 240. 240/16= 15 which is why x= 15 for part A. In part A you write the equation as x/20 = 6/8 which after cross multiplying is 8x = 120. 120 divided by 8 is 15 so x=15 on both parts.
