Answer:
Step-by-step explanation:
First, we have to write 8 + x, but since it's half of that we write it as a fraction with a 2 on the bottom to halve it.
Use the two-way table to answer the question.

Answer:
<u>A.) 11%</u>
Step-by-step explanation:
<u>Step 1)</u> There are 9 favorable outcomes but only 1 outcome is possible, so that leaves us with a fraction of:
<u>Step 2)</u> Then we need to turn this into a decimal to find the percentage:
1 ÷ 9 = 0.111111111...
<u>Step 3)</u> We now need to turn this into a percent:
0.11 x 100% = 11%

Answer:
See the attached figure which represents the problem.
As shown, AA₁ and BB₁ are the altitudes in acute △ABC.
△AA₁C is a right triangle at A₁
So, Cos x = adjacent/hypotenuse = A₁C/AC ⇒(1)
△BB₁C is a right triangle at B₁
So, Cos x = adjacent/hypotenuse = B₁C/BC ⇒(2)
From (1) and (2)
∴ A₁C/AC = B₁C/BC
using scissors method
∴ A₁C · BC = B₁C · AC
