Answer:
1. 60 degrees
2. 50 degrees
4. 49 degrees
5. 26 degrees
Step-by-step explanation:
The sum of the measures of the angles of a triangle is 180 degrees.
1.
x + 80 + 40 = 180
x + 120 = 180
x = 60
2.
x + 75 + 55 = 180
x + 130 = 180
x = 50
4.
x + 90 + 41 = 180
x + 131 = 180
x = 49
5.
x + 81 + 73 = 180
x + 154 = 180
x = 26
Answer:
-7(9) < -56
Step-by-step explanation:
-7(9) is -63 which is less than -56 so anything above that is less than 56-
Answer:
The significant figure of the result is 138.8
Step-by-step explanation:
24.78*(37.3 - 31.72)
Solving the bracket first:
37.3 - 31.72 = 5.58
A zero is added to 37.3 before the substraction, so;
37.3 - 31.72 = 37.30 - 31.72 = 5.58
Following the rule of significant figure; we have the answer of the substraction as 5.6 since the least number of significant is one decimal place.
The new expression will be:
24.78 * 5.6 = 138.768
Therefore, the result of our expression 138.8 by following the rule of significant figure
Answer:
0
Step-by-step explanation:
The smallest (greater or equal to zero) multiple of 13 is 0
to get a positive multiple of 13 you have to multiply 13 by a natural number:
0 = 13×0
13 = 13×1
26 = 13×2
.
.
.
then the smallest one is 0.
