7/8 x 8/3=56/24—simplify—-> 7/3
Answer:
√160
Step-by-step explanation:
For y-intercept, we use y = mx + c. Comparing both, y = mx +c & y = 3x + 12
y intercept = c = 12
Point is (0, 12)
For x intercept, we use y = m(x - d). We have
y = 3x + 12 → y = 3(x - (-4))
Compare both, x intercept = d = - 4
Point is (-4, 0)
Using distance formula,
Distance = √(0-12)² + (-4-0)² = √12²+4²
Distance = √144+16 = √160

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.
