Answer:
<h2> - 320</h2>
Step-by-step explanation:
a₁ = 10
a₂ = 6
d = a₂ - a₁ = 6 - 10 = -4
n = 16
a₁₆ = a₁ + (n-1)•d = 10 + (16-1)•(-4) = 10 - 60 = -50
Write the decimal number as a fraction ( over 1 ) 1.49=1.49/1
Multiplying by 1 to eliminate 2 decimal places we multiply top and bottom by 2 10s
Numerator ( N)
N= 1.49*10*10=149
Denominator(D)
D+ 1*10*10=100
N / D =149/100
Simplifying the fraction:
149/100
149/100
1 49/100 ( Final Answer )

Answer:
x=14
Step-by-step explanation:
x-4=⅓(6x-54)
x-4=2x-18
x+14=2x
x=14
Answer:
∠ ADC = 53°
Step-by-step explanation:
Note the angle between the radius and the tangent is 90°
The sum of the angles in quadrilateral AOCB = 360°, thus
∠ AOC = 360° - (90 + 90 + 74 )° = 360° - 254° = 106°
∠ AOC is twice the angle on the circumference ∠ ADC, thus
∠ ADC = 106° ÷ 2 = 53°
