All triangle add up to 180
so 180-(96+48)
which is 36
so 36 is the missing interior angle
now all lines also equal 180
so 180-36=x
x=144
Answer:
2550 Kilometers
Step-by-step explanation:
850 times 3 equals 2550
Surface area = volume
2πr(h + r) = πr^2h
2h + 2r = rh
rh - 2h = 2r
h(r - 2) = 2r
h = 2r/(r - 2) = 7.2/(3.6 - 2) = 7.2/1.6 = 4.5
surface area = 2πr(h + r) = 7.2(4.5 + 3.6)π = 7.2(8.1)π = 58.32πcm^2
Volume = πr^2h = (3.6)^2 x 4.5π cm^3 = 12.96 x 4.5π cm^3 = 58.32π cm^3

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.
