Answer:
Angle 3 = 180 - 45 - 113 = 22 degrees
Angle 1 = 113 degrees
Angle 2 = 180 - 113 - 22 = 45 degrees
Step-by-step explanation:
Answer:
∠3
Step-by-step explanation:
Supplementary angles are angles that add up to 180°. Angle 6 is a right angle, so it's worth 90°. This means that the other angle(s) have to be 90° as well.
As you can see, the other angle with 90° is angle 3, thus, making it the correct answer.
Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer:
1 i think
Step-by-step explanation:
Let his total money be x.
He spent (3/7)*x of his money.
He gave 1/4(x-3/7x) to his sister.
which is : (1/4)*(4/7)*x = (1/7)*x
Now,
How much money he have in the beginning =
(3/7)*x+(1/7)*x+120=x
(4/7)*x+120=x
120=x-(4/7)*x
120=(3/7)*x
x=120*7/3 [cross multiplication]
x=280.
So, Alex had $280 in the beginning.
