You don't need to answer the first one because i know i'm right on it, just answer 2 and 3.

ok, so you can find angle 4 using the vertical angles theorem, angle 4 is 52 degrees. That was number 2

Number 3. if angle 1 is 50 then using vertical angles will show that angle 4 is also 50 degrees, angle 4 and 5 are complementary meaning that when they are added it is 90 degrees. so subtract 50 from 90 and you are left with 40. Angle 5 is 40 degrees.

so number 2 is 53

number 3 is 40

hope this helps

Step-by-step explanation:

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.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
