To find the value of x, create a proportion. A proportion is two equal ratios for similar figures. The two triangles are similar because they are the same shape but not the same size. Create ratios between corresponding sides of figures.

$\frac{12}{2x+1}=\frac{8}{x+4}$

To solve for x, cross multiply:

12(x+4) = (2x+1)(8)

12x + 48 = 16x + 8

48 = 4x + 8

40 = 4x

10 = x

out of all the 59 candidate who sat for examination 35 did physics 35 also did mathematics while 28 also attempted biology. If 1

alisha [4.7K]

This doesn’t make sense
You say 28 did biology, but then 15 did maths and biology, and 16 did physics and biology
15 + 16 is 31 ??
