Answer:
a) x = 10
Step-by-step explanation:
En este romboide, el angulo A es igual a el angulo C, y el angulo ABC es igual a el angulo CDA.
Entonces, el angulo C es 7x.
En un triangulo, los angulos se suman para ser 180 degrados. En el triangulo BCE, hay un angulo recto.
7x + 2x + 90 = 180
7x + 2x = 90
9x = 90
x = 10

Answer:
yes they are congruent because they have the same size and shape
Step-by-step explanation:
In order to calculate the z-score of a normal distribution, you need to apply the formula:
z = (o - m) / s
where:
o = observed value
m = mean
s = standard deviation
In your case:
z = (259 - 239) / 25 = 0.8
The answer is, indeed, z = 0.8
Answer:
l = gt²/(2π)²
Step-by-step explanation:
if T = 2π√l/g
squaring both sides
(T)² = (2π)² × (√l/g)²
T² =4π² × l/g
T² = 4π²l/g
using cross multiplication techniqes
gT² = 4π²l
divede both sides by " 4π²"
gT²/4π² =4π²l/4π²
gT²/4π² =l
l = gT²/(2π)²
that is the final answer.
