i√5
steps:
negative square root is called a complex number
for a negative square root standard form means have an i in the number
i = √-1
standard form for a complex number is
a+bi
√-5 = √5 x √-1

Step-by-step explanation:
Answer:
1/3
Step-by-step explanation:
-3 - -1= -2
3-9 = -6
-2/-6 = 2/6 = 1/3
Answer:
By comparing the ratios of sides in similar triangles ΔABC and ΔADB,we can say that 
Step-by-step explanation:
Given that ∠ABC=∠ADC, AD=p and DC=q.
Let us take compare Δ ABC and Δ ADB in the attached file , ∠A is common in both triangles
and given ∠ABC=∠ADB=90°
Hence using AA postulate, ΔABC ≈ ΔADB.
Now we will equate respective side ratios in both triangles.

Since we don't know BD , BC let us take first equality and plugin the variables given in respective sides.

Cross multiply

Hence proved.
