H is the altitude of a right triangle, so h²=AD*DC=(20-4)*4=64
h=√64=8
D is the correct answer.
Answer:
Step-by-step explanation:
41 + 4x = 7x + 5(Exterior angle theorem)
36 = 3x
Hence x = 12
This is how I figure these type of questions out you can draw a circle on the J,K,L the trace it to make a triangle it should be less then 90 degrees if not then you might’ve traced it wrong.
3/5 • 4/5 = 12/25.
This would be the solution to the above question, simply multiply both the numerator and denominator together to get the final answer.
