Answer:
<em>x=8</em>
Step-by-step explanation:
We have to write and equation for this. We will say that x is the unknown. Let's work backwards: 5 more than half the number. That is 1/2x+5. We will put that on one side. The other side is this: 15 less than 3 times the number. This is 3x-15. Then, we put it together: 3x-15 = 1/2x+5. First, subtract 5 from both sides. Then multiply both sides by two. You will get 6x-40 = x. Then add 40 to get 6x = x+40. Subtract x from the sides: 5x = 40. x=8
Answer:
43°
Step-by-step explanation:
In a isosceles triangle, two angles HAVE to be equal.
This means that 94 can be one of the angles that are equal, or the angle that is not equal to another angle.
Let's start with the fact that 94 can be one of the angles that are equal. (Note: angles in a triangle add up to 180)
94+94+x=180
188+x=180
There is NOT a possible value for x in this situation, as you cannot have a negative value of an angle. Therefore we must try the other situation where 94 is the angle that is not equal to another angle.
x+x+94=180
2x+94=180
Subtract 94 from both sides
2x=86
Divide both sides by 2
x=43
Therefore the answer is 43°
