Answer:
no because 1.9 is less then 2.7 so the thing is wrong
To solve the value of x we use the sine rule that states.
a/sinA = b/sinB = c/sinC
Where a, b, and c are the opposite sides of angle A, B. and C respectively.
x/sin60 = 7/sin80
x =(7sin60)/sin80
= 6.062/0.9848
=6.155696691
To 3 significant figures the answer is 6.16
Answer:
127 degrees.
Step-by-step explanation:
These angles are corresponding angles so they have the same measurement.
The value of y would be zero in that problem
2= 2y - x
23 = 5y - 4x
isolate the x in the first equation
x = 2y - 2
now use this to substitute x in the second equation
23 = 5y - 4 (2y - 2)
23 = 5y - 8y + 6
23 = -3y + 6
-3y = 17
y = -5 2/3 (5.6 repeating )
now use that to find x in either equation.
2 = 2 (-5.66666) - x
2= -11.3 repeating - x
13.3 repeating = -x
x = -13.3 repeating
optional ** use the second equation to check
