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.
<span>vertical angles
m<A = m<B
so
</span>4x - 10 = <span>6x - 30
6x - 4x = -10 + 30
2x = 20
x = 10
m<A = </span><span>4x - 10
</span>m<A = 4(10) - 10
m<A = 40 - 10
m<A = 30<span>
</span>
