<span>2x + x = 12
=> x =12/3 =4
so, original number is 84. </span>
Answer:
Answer A
Step-by-step explanation:
Approach 1
B, C, and D are wrong because angles 1 and 2 are congruent.
Therefore your answer of both being 60°
Approach 2
Let x = angle 1.
360/x = 6
x = 60°.
Therefore Angle 1 is 60°
An interior angle of a hexagon is 120°
Let y = angle 2.
y is half of 120°
So 120/y = 2
y = 60°
the dot plot, because box plot only shows the 5 number summary and histograms show ratios
It’s n-1 because 1 less than a number(n) would be n-1 and you may think what about 1-n, the words for that is one Minus a number or a number less than 1 but since it’s not that the answer is
N-1
Answer:
(190-5a)°
Step-by-step explanation:
Sum of internal angles of a triangle equals to 180°
If the third angle is x, then we have:
- (2a-32)°+(3a+22)° +x = 180°
- (5a- 10)° +x= 180°
- x= (180+10-5a)°
- x= (190-5a)°
The third angle is: (190-5a)°
