I need help with something! Can anyone help?

big triangle angle:

D is a right angle so it would be 90 degrees. angle E is 53 degrees and then thats when you should add 90 and 53 which equals 143 degrees. a whole triangle has 180 degrees in it, so you subtract 180 and 143 which gets you 37.

big triangle length:

if you look at the small triangle you see 5 and 3, you do 20 divided by 5 which equals 4, so you do 4 times 3 which equals 12. so thats the missing length of the big triangle

small triangle angle:

A is a right angle so it would be 90 degrees. angle C is 37 degrees and then thats when you should add 90 and 37 which equals 127 degrees. a whole triangle has 180 degrees in it, so you subtract 180 and 127 which gets you 53.

small triangle length:

if you look at the small triangle you see 20 and 16, you do 20 divided by 5 which equals 4, so you do 16 divided by 4 which equals 4. so thats the missing length of the small triangle

hope i helped
