Answer:
254,625
Step-by-step explanation:
15. 99%, 0.95, 5/9, 9.5%
Make all decimals: .99, .95, .55, .095
List: Zero is less than 9 or 5 so it's first than 5 and than 9, you have two 9's so 5 is less than 9: .095, .55, .95, .99
16. 3/8, 50%, 0.35, 38%
Same steps: .375, .50, .35, .38
3 is less than 5 and 5 is less than 8 or 7 so: .35, .375, .38, .5
And do the same thing for the other two problems :)
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
