Can someone me with these questions. i dont get this and i will give you brainliest.

1: This is correct because m∠GHJ is less than 90°, which means it is acute. To help you remember this, think of the word "cute" in acute, and relate that to small. Small angle=cute size=acute angle

2: The correct answer is Obtuse. This is because the angle is larger than 90°. To help you remember this think of the word obese, which sounds similar to obtuse. Obese means very large, so the very large angle is obtuse.

Hope that helps!

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.
