Which of the following can be used to construct a triangle? A ) 4cm 12cm 8cm
B) 5cm 12cm 10cm
C) 16cm 4cm 6cm
D) 30cm 12cm 6cm

unless if u could do my questions, if not i wouldn't want to

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
