Answer:
B) No Unique Solutions
Step-by-step explanation:
Given:
now we now the value of y = 2 so we will substitute in equation
Now, We have value of y=2 and value of Substituting in both the value in equation
which means that the equation has Infinite solutions.
X = 15
X + 90 = 7x
X = 7x - 90
X - 7x = -90
-6x = 90
Divide both sides by -6
X = 15
Answer:
2.964
Step-by-step explanation:
Ok so cos(x) = sin(90-x) so using that you can get sin(7x-15) = sin(90-(3x+5)) so 7x-15 = -3x+85. 10x = 100 and x = 10. Use that to find the 2 angles are 55 and 35
