Answer:
C
Step-by-step explanation:
The 2 angles lie on a straight line and sum to 180° , then
5x + 19 + 8x = 180
23x + 19 = 180 ( subtract 19 from both sides )
23x = 161 ( divide both sides by 23 )
x = 7
Then
∠ OML = 15x + 19 = 15(7) + 19 = 105 + 19 = 124° → C
Answer:
x = 2.
Step-by-step explanation:
I am taking this to mean
2^3 * x^3 = (2 + x)^3
8x^3 = (2 + x)(4 + 4x + x^2)
8x^3 = 8 + 8x + 2x^2 + 4x + 4x^2 + x^3
7x^3 - 6x^2 - 12x - 8 = 0
7(2)^3 - 6(2)^2 - 12(2) - 8
= 56 - 24 - 24 - 8 = 0
x = 2.
This is the only real root.
By definition, the formula of the period of a pendulum is given by:
From here, we must clear the value of l.
We have then:
Raising both members to the square we have:
Then, passing gravity to multiply, we have:
Answer:
When clearing we have:
Answer:
x = 8
Step-by-step explanation:
The triangle is isosceles with legs congruent, both x
Using Pythagoras identity in the right triangle
x² + x² = 16²
2x² = 256 ( divide both sides by 2 )
x² = 128 ( take the square root of both sides )
x = = = × = 8
