Answer:
ASA
Step-by-step explanation:
Given:
Two triangles ABC and EDC such that:
AB ⊥ BD and BD ⊥ DE
C is the midpoint of BD.
The two triangles are drawn below.
Since, AB ⊥ BD and BD ⊥ DE
Therefore, the two triangles are right angled triangle. The triangle ABC is right angled at vertex B. The triangle EDC is right angled at vertex D.
Since, point C is the midpoint of the line segment BD.
Therefore, C divides the line segment BD into two equal parts.
So, segment BC ≅ segment CD (Midpoint theorem)
Now, consider the triangles ABC and EDC.
Statements Reason
1. ∠ABC ≅ ∠CDE Right angles are congruent to each other
2. BC ≅ CD Midpoint theorem. C is midpoint of BD
3. ∠ACB ≅ ∠ECD Vertically opposite angles are congruent
Therefore, the two triangles are congruent by ASA postulate.
So, the second option is correct.
Answer:
solution given:
For triangle
side1=9ft
side2=10ft
base[b]=11ft
height[h]=7.7ft
and for rectangle
length [l]=3ft
wide [w]=9ft
Now
total surface area=lateral surface area +2curved surface area
=perimeter of triangle×length +2area of triangle
=(9+10+11)×3+2×1/2×2(½×b*h)
=90+11×7.7
=174.7
=175ft²is a required answer.
Answer:
184.68cm
Step-by-step explanation:
19x3.6=68.4
68.4x2.7=184.68
I think the answer is C. and you accidentally put the dot in the wrong place.
x = 5
Step-by-step explanation:
- 3 ( 2x - 1 ) + 4x = 4 ( 3x - 1 ) - 9
- 6x - 3 + 4x = 12x - 4 - 9
- 10x - 3 = 12x - 13
- - 3 + 13 = 12x - 10x
- 10 = 2x
- x = 10 / 2
- x = 5

1 gallon is 4 quarts or 8 pints. 9 gallons - 3 gallons= 6 gallons
Then convert it to quarts so, 6×4=24 quarts.
Then subtract that by 10 quarts so, 24-10=14 quarts.
Because you requested the number in pints, you have to convert it again and because there are 2 pints in a quart you multiply it by 2 so, 14×2=28 pints left over.
