we know that
If line WX is perpendicular to line YZ
then
see the attached figure to better understand the problem
m∠WVY=90°--------> 4a+58=90-----> 4a=90-58-----> a=32/4------> a=8°
m∠XVY=90°--------> 2b-18=90----> 2b=90+18------> b=118/2-------> b=59°
therefore
<u>the answer is</u>
a) The value of a is 8 degrees
b) The value of b is 59 degrees
Answer: it’s a
Step-by-step explanation:
$70/$32.55=$37.45 the amount of money she spent on coffee. We can divide that amount by $7.49 to see how many pounds she brought $37.45/$7.49=5
She brought 5 pounds of coffee.
Take the complex zero 1+i. There must be another zero 1-i to balance it, so we have the factors (x-1-i)(x-1+i)=x²-2x+1+1=x²-2x+2.
So the polynomial is (x+3)(x²-2x+2)=x³-2x²+2x+3x²-6x+6=x³+x²-4x+6, option D.
Answer:
1 : 2
Step-by-step explanation:
5 cm : 10 cm ← divide each part by 5 cm
= 1 : 2
