<span>The interior angle of a square is 90 degree.
That is 2X-10=90 degree
add 10 on both sides
2X=100
divide both side by 2
X=50.</span>
Answer:
C) 75
Step-by-step explanation:
I got this because what you have to do, they all have to add up to 180. so what you do is:
2x + 30 = 180
-30 -30
2x = 150
2x/2 = 150/2
x = 75
Answer:
The area of a triangle can be determined with the two side lengths, the length and breadth/width multiplied.
x = unknown value of breadth/width
23 = length
506 = the area of the two lengths multiplied
23(x) = 506
/23 /23
x = <u>22</u>, 22 metres is it's breadth.
Answer:
Total distance traveled= 21h miles
Step-by-step explanation:
You biked at 10 mph for h hours
Speed= 10 mpg
Time = h hours
Distance covered= speed*time
Distance covered= 10h miles
walked at 3mph for twice as long as I biked,
Speed= 3 mph
Time= twice as long as biked
Time= 2(h) hours
Distance= 2h*3
Distance= 6h miles
ran at 10mph for one quarter as long as I walked
Speed= 10 mph
Time= 1/4 of(2h)
Time= 1/2h hours
Distance= 1/2h*10
Distance= 5h miles
Total distance traveled
= 10h miles +6h miles+ 5h miles
Total distance traveled= 21h miles
