Answer:
Lengths to be added are converted into cm.
15 m 18 cm = 1500 cm + 18 cm = 1518 cm
16 m 22 cm = 1600 cm + 22 cm = 1622 cm
Now, sum
1 1
1518 cm
+ 1622 cm
3140 cm
= 31 m 40 cm
Therefore, 15 m 18 cm + 16 m 22 cm = 31 m 40 cm
Step-by-step explanation:
Answer:
B = 25 because 180-25-130 = 25 and all angles within triangle add to 180 degrees
a = 6 because the triangle is isosceles and we can see symmetry and draw this to prove on two opposite lines, therefore we can now find height easier.
c = 10. 876 because 130/2 = 65 degree and with new central height we can find Right Angle and using 6 x sin (65) = 5. 438 then we multiply by 2 to find c
Then all you have to do is re-write and round to the nearest 10th and check the units and write degree sign where required.
Step-by-step explanation:
The horizontal line is refered to as a fraction bar or a vinculum. There are also other names, but these two are the ones I know the best.
