Answer:
D: 6√30
Step-by-step explanation:
Simplify the following:
sqrt(20) sqrt(3) sqrt(18)
sqrt(18) = sqrt(2×3^2) = 3 sqrt(2):
sqrt(20) sqrt(3)×3 sqrt(2)
sqrt(20) = sqrt(2^2×5) = 2 sqrt(5):
2 sqrt(5) sqrt(3)×3 sqrt(2)
2×3 = 6:
6 sqrt(5) sqrt(3) sqrt(2)
sqrt(5) sqrt(3) sqrt(2) = sqrt(5×3×2):
6 sqrt(5×3×2)
5×3 = 15:
6 sqrt(15×2)
15×2 = 30:
Answer: 6 sqrt(30)
Answer:
131.7
Step-by-step explanation:
The complement is what adds to an angle to get 90 degrees
so
x is 25 mroe than 4 times y
x+y=90
x=25+4y
sub 25+4y for x
25+4y+y=90
25+5y=90
minus 25 both sides
5y=65
divide both sides by 5
y=13
sub back
x+y=80
x+13=90
x=77 degrees
25/66
5/6 x 11/5
5/6 x 5/11
5 x 5
6 x 11
25/66
Answer:
Value of x is 34
Step-by-step explanation:
The figure is a quadrilateral;
Angles given are; 2x°, 88°,108° and (3x - 6)°
We already know that the interior angles of a quadrilateral add up to 360°
Therefore, to get the value of x;
2x° + 88° + 108° + (3x - 6)° = 360
5x° + 190° = 360°
5x° = 170°
x = 34°
Thus, the value of x is 34
