We're given D = 83 and E = 11. Let's find the missing angle F
D+E+F = 180
83+11+F = 180
94+F = 180
F = 180-94
F = 86
Since the triangle has angles
D = 83
E = 11
F = 86
We can say the following:
- FD is the shortest side (since it is opposite the smallest angle E = 11)
- ED is the longest side (since it is opposite the largest angle F = 86)
- That puts side EF as the medium length side of the triangle.
- All three angles of this triangle are less than 90, so this triangle is acute.
- Also, all three angles are different which makes this triangle scalene as well.
Answer:
1) x³-y³ = (x-y)(x²-xy+y²)
2)x²-y² =(x-y)(x+y)
3)x-y = (x-y)
hcf = (x-y)
lcm = (x-y)(x²-xy+y²)(x+y)= (x³-y³)(x+y)
Step-by-step explanation:
Answer:
ΔNPM and ΔOMP by SAS postulate
B is correct
Step-by-step explanation:
In ΔNPM and ΔOMP
NP = OM (Given)
∠NPM = ∠OMP (Given)
PM = MP ( Common )
So, ΔNPM ≅ ΔOMP by SAS property of concurrency.
ΔNPM and ΔOMP are congruent because their two side and angle between them are equal.
Therefore, SAS postulate use here
Hence, ΔNPM and ΔOMP by SAS postulate
Answer:
C = 5
Step-by-step explanation:
Distribute the 3
3c - 18 + 6c = 27
Adding like terms
9c - 18 = 27
Add 18 to both sides
9c = 45
Dividing both sides by 5
C = 5
