If two triangles are similar their angles are all the same.
Answer:
We have, 15% × x = 85
or,
15
100
× x = 85
Multiplying both sides by 100 and dividing both sides by 15,
we have x = 85 ×
100
15
x = 566.67
Answer:
Let x = the number of marbles Tim has
Let 2x = the number of marbles Sue has
x + 2x + 15 = 63
3x = 48
x = 16 marbles
