We can use the following rule of surds to solve the problem:
,
which means that when multiplying two numbers with the same bases, we can simply add their powers while keeping the base the same.
Applying this rule:

Answer:
1) 34º
2) 52º
3) 56º
4) 94º
Step-by-step explanation:
let 3 be x
let 1 be y
let 2 be z
let 4 be j
180=86+38+x 56=x
90=56+y 34=y
180=86+j 94=j
180=34+z+94 52=z
2 2/3 x 3/11
= 8/4 x 3/11
= 24/44
Simplified
6/11
(X)+2(x+1)=26
3x=24
X=8
Y=x+1
Y=8+1
Y=9
The two numbers are 8 and 9
The operations must take account of the place values of individual digits in the numbers.
