Answer:
(d) 16
Step-by-step explanation:
Angles opposite sides of the same measure are congruent. Here, the triangle is isosceles, so the base angles are congruent:
2x = 32
x = 16 . . . . . . divide by 2°
We can create a equation to find out.
since we are finding a number where when multiplied by 1.25(this is the decimal form of the percentage) gives us 25, we know that the number we are finding is less than 25. here is the equation.
1.25(x)=25
divide both sides by 1.25 to get "x" alone.
x= 20
It would be 15x/9x
Hope this helps
Answer:
it (6,18,23)
Step-by-step explanation:
Answer:
100%+15% = 115%
proportionally:
x - 100%
161 - 115%
x = (161 * 100%) / 115% = 140
