For this type of problem the way to do it is..
1) add the inside of the triangle, in this case it is --> 132 + (2×+4) and then you set it equal to the number that's outside the triangle which is 112
2) and then you solve .... 132+4=136
3) your equation should look like ---> 2×+136=112
4) you subtract 136 from both sides
5) you get 2×= -24
6) divide 2 from both sides.. and you get ×=-12
that's if they are asking for the value of X
if they want to go further... you plug in the value of x in which we found was -12 into the angle above... I hope I helped.
Answer:
120 ways
Step-by-step explanation:
This can be solved through analytical combination.
First, select the president; this implies selecting one person out of five people, which is in 5 ways.
Secondly, select the vice president, this implies selecting one person out of four people, since one position has been taken by the president already leaving only four people which is in 4 ways
Thirdly, select the secretary, this implies selecting one person out of three remaining people, which is in 3 ways
Lastly, select the treasurer, this implies selecting one person out of two remaining people, which is in 2 ways
Therefore, ways by which a president, vice president, secretary, and treasurer can be elected is
5 x 4 x 3 x 2 = 120 ways
Answer:
Should be 36°
Step-by-step explanation:
If you add up the angle measurements of the shape, it should equal 360° (This applies to all shapes)
So 360° divided by 10 (# of angles)= 36° (Per angle)
Answer:
23
Step-by-step explanation:
The pattern is adding by 5
