If all angles are equal it must be an equilateral triangle which means the measure of Y is 60°
Is this the whole equation?
Step-by-step explanation:
Cuz if not we need the whole question
There are many ways to solve simultaneous linear equations. One of my favorite for finding integer solutions is graphing. The attached graph shows the solution to be ...
... (x, y) = (4, 7)
_____
You can also use Cramer's Rule, or the Vedic math variation of it, which tells you the solution to
is given by
Here, that means
... x = (9·67-5·75)/(9·8-5·3) = 228/57 = 4
... y = (75·8-67·3)/57 = 399/57 = 7
_____
A (graphing) calculator greatly facilitates either of these approaches.
Answer:
A
Step-by-step explanation:
just take the parenthesis off because in this equation you can just ignore them.
