Answer:
The answer is 753.01 m².
Step-by-step explanation:
Given that the formula of sector is θ/360×π×r² where r represents radius of circle. Then, you have to substitute the values into the formula :
Let θ = 255°
Let π = 3.14,
Let r = 18.4m,
Answer:
-i^5=-i
Step-by-step explanation:
rewrite the equation ;
i^4=1
I^4 *-i = 1*-i=-i
Answer: c
Step-by-step explanation:
The two points on the line are open, so they will not be included in the solution set, which means they will be greater than or less than. No number can fit both inequalities, so it must be “or”. The only one that fits this is c.
Answer:
The answr is 102 degrees. Here's why
Step-by-step explanation:
The square means the angle is 90 degrees. Therefore, for the big triangle, we already know 2 of the degrees, 50 and 90. A triangle's degrees add up to 180. 50+90=140. 180-140=40. This means the top angle is 40. Now finding X is easy, because we already know the other 2 points in the triangle, which are 38 and 40. Add those up, you get 78. 180-78=102, your answer. The triangle is 102 degrees.
