Answer:
b
Step-by-step explanation:
∠ BAD = 90° and
∠ DAC + ∠ CAB = ∠ BAD, that is
x + 2x - 30 = 90
3x - 30 = 90 ( add 30 to both sides )
3x = 120 ( divide both sides by 3 )
x = 40 → b
Answer:
4.16 in^3
Step-by-step explanation:
Given data
Volume of sphere= 4/3πr^3
Radius= 1 inch radius
Substitute
Volume of sphere= 4/3*3.14*1^3
Volume of sphere= 4/3*3.14*1
Volume of sphere= 4*1.04
Volume of sphere= 4.16 in^3
<h2>9</h2>
Step-by-step explanation:
x² - 9x = 36
x² - 9x - 36 = 0
x² + 3x - 12x - 36 = 0
x ( x + 3 ) - 12 ( x + 3 )
( x - 12 ) ( x + 3 )
x = 12, -3
sum = 12 + (-3)
= 12 - 3
= 9
