A.
because the total distance of every triangle 180. Add the two other angles so 42+ 57 =99. Then you have to subtract those two combined angles to find the missing one from the total distance, which is 180. 180-99=81. the answer is A. 81
Answer:
If it is ax^2 + bx + c = 0 then it is a quadratic equation
Step-by-step explanation:
<h3>
Answer: B. 781.6 feet approximately</h3>
=======================================================
Work Shown:
The horizontal portion is 400+166 = 566 feet. Label this as 'a', so a = 566. The vertical side is unknown, so b = x. The hypotenuse is c = 965
Use the pythagorean theorem
a^2+b^2 = c^2
566^2+x^2 = 965^2
x^2 = 965^2 - 566^2
x = sqrt( 965^2 - 566^2 )
x = 781.58108984289 which is approximate
x = 781.6 feet when rounding to one decimal place
Answer:
JL = 31
Step-by-step explanation:
JL is the total length of the line segment. We know that JK is 15 units long and that KL is 16 units long. So, you would add these numbers (15 & 16) together to get the total length of the line segment. Hope this helps! :)
The dropdown numbers is an illustration of combination
The smallest dropdown number is 1025
<h3>How to determine the smallest dropdown number?</h3>
From the question, we have the following parameters:
- The dropdown number is 4-digit
- The digits are different.
We start counting from 1023, 1024, 1025, 1026...........
- The sum of digits in 1023 is 6, and the average is 1.5
- The sum of digits in 1024 is 7, and the average is 1.75
- The sum of digits in 1025 is 8, and the average is 2
The number 1025 satisfies the given conditions
Hence, the smallest dropdown number is 1025
