Answer:
60° and 30°
Step-by-step explanation:
I'm going to assume you mean complementary angles.
Complementary angles are angles that form 90° or a right angle
From the question, it is saying that
(5x) +(4x-18) = 90
To work out x, solve the equation
9x-18 = 90
9x = 108
x = 12
Therefore the angle of 5x is 5x12 or 60° and the angle of (4x-18) is going to be 4x12-18 = 30°
A.) Here, w = 550kg/m^3.
Therefore, S = (0.032(550) - 2.5)/10000 = 0.00151
After drying, the beam will be (1 - 0.00151) x 12.027 = 12.009
b.) 0.0012 = (0.032w - 2.5)/10000
0.032w - 2.5 = 12
0.032w = 12 + 2.5 = 14.5
w = 14.5/0.032 = 453 kg/m^3
Therefore, the required water content is 453 kg/m^3
Step-by-step explanation:
here's your solution
=> volume of circular cone = (1/3)πr^2h
=> radius = 4 cm ,, height = 9 cm
=> volume of cone = (1/3)*(22/7)*16*9
=> volume of circular cone = 150.8 cm^3
Answer:
x = 17/4 = 4.25
Step-by-step explanation:
We assume your multiplication symbol (×) is intended to be a variable (x).
Simplifying, we have ...
17 -10x +45 = 6x -10 +4
68 = 16x
68/16 = x = 17/4 = 4.25

<em>Check</em>
17 -5(2(4.25) -9) = -(-6(4.25) +10) +4
17 -5(8.50 -9) = -(-25.5 +10) +4
17 -5(-0.5) = 15.5 +4
17 +2.5 = 19.5 . . . . . . true
3/4x+5/6=5x-125/3
3/4x+5/6-5/6=5x-125/3-5/6
4/3x=5x-85/2
4/3x-5x=5x-5x-85/2
-17/4x=-85/2
(-4*-17/4x)=(-85/2*-4)
17x=170
x=170/17
x=10
