Answer:

70º

Step-by-step explanation:

A straight line is 180º   You should know that a right angle is 90º

90+20=110

Next you need to subtract 110 from 180

And you get 70

I hope that this is the right answer!

Answer:

70 degrees

Step-by-step explanation:

Straight angles always equal 180 degrees

One angle is 20 degrees and the angle with the box is 90 degrees

90+20=110

180-110=70

\left \{ {{a+b=87} \atop {a-3b=7}} \right.



a-3b=7
a=7+3b

a+b=87
(7+3b)+b=87
7+4b=87
4b=87-7
4b=80
b=20

a=7+3b
a=7+3*20
a=7+60
a=67
