Answer:
∠3 = 81
Step-by-step explanation:
Interior angles in a triangle add up to equal 180°
Hence, 58° + 41° + ∠3 = 180
58 + 41 = 99
99 + ∠3 = 180
* subtract 99 from each side *
99 - 99 cancels out
180 - 99 = 81
we're left with ∠3 = 81°
Answer:
3 1/4
Step-by-step explanation:
3/4 + (1/3 divided by 1/6) - (- 1/2)
first calculate between the brackets.
(1/3) / (1/6)
Division is the inverse of multiplying.
(1/3) * (6/1)
multiply both numerators and multiply both denominators
1*6 / 3*1 = 6/3 = 2
3/4 + (2) - (- 1/2)
make all denominators into 4
3/4 + (8/4) - (- 2/4)
- ( - = plus
3/4 + (8/4) + 2/4
3/4 + 8/4 + 2/4
add all numerators since the denominators are all the same.
( 3 + 8 + 2 ) / 4
13/4

Answer:
41.13m
Step-by-step explanation:
the circumference of the circle is 25.13 and the 8 on both sides equals to 16
You would write it as 25,000 or it would be 0.025
