Answer:
x = 2
z = 93°
Step-by-step explanation:
Opposite angles are equal
9x + 69 = 87
9x = 87 - 69
x = 2
A straight line is 180°
180 - 87 = z
z = 93°
<u>We are given: </u>
Density of glass in g/cm³ = 2.5
<u>Finding the density in kg/m³: </u>
In converting 2.5 g/cm³ to kg/m³, we will first convert the g to kg
<u>Converting the g to kg:</u>
2.5 g/cm³ * 1
Since 1kg = 1000g, <em>1kg/1000g = 1</em>
2.5 g/cm³ * 1kg / 1000g
the g in the numerator and the denominator will cancel out and we will get:
2.5 kg / 1000 cm³
<u>Converting the cm³ to m³:</u>
We know that 1 m³ = 10⁶ cm³
So, 10⁶ cm³ / 1 m³ = 1
Multiplying the density by 1
2.5 kg / 10³ cm³ * 1
2.5 kg / 10³ cm³ * 10⁶ cm³ / 1 m³
the cm³ in the numerator and the denominator will cancel out
2.5 * 10⁶ kg / 10³ m³
2.5 * 10³ * 10³ kg / 10³ m³
2.5 * 10³ kg / m³
2500 kg/m³
7 + 14 + 21 + ... + 105 =
= 7(1 + 2 + 3 + ... + 15)
= 7(15)(16)/2
= 840
