In a test Simba was asked to find the size of PÂR
He was given that in the diagram PQ//AR and PA//QR. QR=SR and PQA = 90° and SR = 30°
Simba's answer is written below the sketch. Simba is lazy and didn't bother to put in any
reasons. Copy down Simba's answer and fill in the missing reasons.

b. they are parallel and will never intersect.

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.

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.
