we know that
The sum of the internal angles of a triangle must be equal to
degrees
see the attached figure with letters to better understand the problem
m∠B+
°-----> by supplementary angles
m∠B=
m∠A=
m∠C=
m∠A+m∠B+m∠C=
Substitute

therefore
the answer is
the value of x is equal to 
Answer:
y = 3
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through.
here the line passes through (0, 3) with y- coordinate 3
y = 3 ← is the equation of the horizontal line
The least common multiple of each is 120
Maximum value if this parabola is 7 when x=6 giving the coordinate (6,7) so 7 is your answer
Answer:
Step-by-step explanation:
The area of a sector has the formula
Hopefully, this looks somewhat familiar to you. Theta is the central angle given as 75, r is the radius given as 4. Filling in:
and simplifying that a bit to look less threatening, but not by much:
and
Not sure how you're supposed to express your answer so I gave both the fraction and its decimal equivalency.
