Answer:
Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (sum of angles of a triangle)
Step-by-step explanation:
The answer is self-explanatory. The sum of interior angles of a triangle is 180°.
Answer:
Step-by-step explanation:
<u>Use the law of cosines:</u>
- cos C = (a² + b² - c²)/(2ab)
<u>Apply to the given triangle and solve for x:</u>
- cos x = (52² + 48² - 70²)/(2*52*48)
- cos x = 108/4992
- cos x = 0.02163461538
- x = arccos 0.02163461538
- x = 88.76°
Answer:
10
Step-by-step explanation:
2 legs because you walked into the room and 4 legs of the bed and 4 legs of the chair.
A/b times b/c is = ab/bc
which can be written as a/c times b/b
anything over itself is 1 so b/b is one
a/b times b/c = a/c
Answer:
976 421; 124 679
Step-by-step explanation:
Part A. Largest number
Leslie's number was 976 421.
This is because the largest numbers are in the positions of largest value.
For example, 9 in the hundred thousands place, the next largest number in the ten thousands place, and so on.
===============
Part B. Smallest number
The smallest possible number is 124 679.
The value of the 4 is greater than the value of the 6 because the 4 is in the thousands place and the 6 is only in the hundreds place.
4000 > 600.
