Answer: Multiply the top equation by , multiply 3 the bottom equation by 2, then add the equations.
Step-by-step explanation:
6x - 15y = 39
+ (- 6x + 4y) + (26)
- 11y = 65
Answer:
Hence, the height of the tree is 14.3 feet.
Given:
AC is perpendicular bisector of BD
AB ≅ AD
To prove:
ΔABC ≅ ΔACD
Solution:
In triangle ABC and triangle ACD,
Step 1: Given
AC is perpendicular bisector of BD and
AB ≅ AD (Side)
Step 2: By perpendicular bisector definition,
BC ≅ CD (Side)
Step 3: By reflexive property,
AC ≅ AC (Side)
Step 4: By SSS congruence criterion,
ΔABC ≅ ΔACD
Hence proved.
1/4 was spent
so 4/4-1/4=3/4 was left
3/4 of withdrawn=90
times both sides by 4/3
withdrawn=360/3=withdrawn
withdrawn=120
he withdrew $120
Answer:
AC = 6.7
Step-by-step explanation:
If this is a 90 degree triangle which I am assuming it is you would the Pythagorean theorem c^2 = a^2 + b^2 since bc seems long I am using that as the hypotenuse.
9^2 = 6^2 + b^2
81 = 36 + b^2
81-36 = b^2
45 = b^2
6.7 = b
so AC = 6.7
