Will give 30 points if answered

I do not like maths.

But, I believe the answer is equal to the number 31

Step-by-step explanation:

Since three yellow dinosaurs are equal to nine, we can estimate that each dinosaur has a value of 3. Since the blue and green dinosaurs added are equal to the number 28, all we have to do is add 3(from the yellow dinosaur) to 28, which is equal to the number 31.

let me know if it is wrong.

Goodbye.

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.
