Answer:
Step-by-step explanation:
We can rewrite 7 as 3+4 then instead of 3*7 we have 3*(3+4).
Then distribute the 3 in the parenthesis 3*(3+4) = (3*3) + (3*4)
First of all, we know that a line is 180°. This means if we add the angles of 61°, 57°, and angle y, we should get 180<span>°.
Simplify:
Subtract 118° to both sides:
We also know that all three angles of a triangle add up to 180<span>°. So we have:
Simplify:
Subtract 129° to both sides:
