Answer:
Step-by-step explanation:
in complementary angles sum of two angles is always 90 degree .
2x+18+6x-8=90
8x+10=90
8x=90-10
x=80/8
x=10
angle B=6x-8
=6*10-8
=60-8
=52 degree
therefore angle B is 52 degree
Answer:
5 meters
Step-by-step explanation:
If the smallest rectangle has a length of 8 meters, and a perimeter of 24 meters then its width is given by:
We can conclude that the width is half of the length for both rectangles. Therefore, the width of the larger rectangle, with a perimeter of 30 meters, is:
The width of the original rectangle is 5 meters.
Answer:8 π inches
Step-by-step explanation:The formula for circumference is diameter *
π
The radius of a circle is always exactly half of the circles diameter.
Therefore, the diameter will be 8 inches
Multiply the diameter, 8 by π
to determine the circumference.
Answer:
16
Step-by-step explanation:
9 divided by 6 is 1 but leaves 3 leaving 36 divide that by 6 so 16
9/10=180/x
x=200
8/10=180/x
(180*10)/8
(180*5)/4
x= 225
225-200=25
Answer: 25
