Explanation
The sum of the three angles of a triangle has to be equal to 180 degrees.
So...
180-(75+50)
180-125
=55 degrees
X equals 55 degrees
Answer:
x + 150 deg = 180deg (being co-interior angles)
:. x = 30 deg
2. y^2 + 7= 32 ( opposite sides of parallelogram are equal)
or, y^2 = 25
or y^2 = 5^2
: . y = 5
3. k= 2y^2 ( opposite sides of parallelogram are equal)
or, k = 2× 5^2
: . k = 50
Answer:
B
Step-by-step explanation:
Using the cofunction identity
sin(90 - x)° = cosx°
Here x = 25° , then
cos25° = sin(90 - 25)° = sin65°
