Answer:
divide the equation by 5
Step-by-step explanation:
all the components are factors of 5 so if we divide by 5, then we get as x² - 2x = -1
Answer:
MN = 3.03 ≈ 3
Step-by-step explanation:
Given: In ΔMNK MN = NK , m∠N = 110° and MK = 5.
To find: MN = ?
Sol: In ΔMNK,
∠M + ∠N + ∠K = 180° (sum of angles of a triangle)
2∠M = 180° - 110° ( ∠M =∠K since MN = MK)
∠M = 70°/2 = 35°
∴ ∠M = ∠K = 35°
Now, Using Sine Rule for finding sides,
Now ∵ sin 35° = 0.57 and sin 110° = 0.94 approx.
By substituting these values in above expression,
k = 
k = 3.03
Therefore, MN = 3 approx.
I'm going to assume you want to find the third side of a triangle. We can use the pythagorean theorem to solve; a^2 + b^2 = c^2
a = 5
b = 3
c = ?
Solve.
5^2 + 3^2 = c^2
25 + 9 = c^2
34 = c^2
√34 = √c^2
5.8 ≈ c
Best of Luck!
For the first drawing, there are 30 tickets altogether, and Jason
has 10 of them. The probability that one of his tickets will win is
10 / 30 .
For the second drawing, there are 29 tickets altogether, and Jason
has 9 of them. The probability that one of his tickets will win is
9 / 29 .
For the third drawing, there are 28 tickets altogether, and Jason
has 8 of them. The probability that one of his tickets will win is
8 / 28 .
The probability that all three of these things will happen is
(10/30) x (9/29) x (8/28) = 720 / 24,360
= 6 / 203 = 2.96 percent (rounded)
