Answer:
x = 20
Step-by-step explanation:
The two angles are complementary angles, which means they add to 90 degrees
2x+7 + 43 = 90
Combine like terms
2x+50 = 90
Subtract 50 from each side
2x+50-50 = 90-50
2x = 40
Divide each side by 2
2x/2 = 40/2
x = 20
Answer:
the answer should be 8.9
you square 12 and square the 8 and subtract them by each other
Answer:
The correct answer is A. 15.2 units
Step-by-step explanation:
The segment AB is congruent to the segment BC eg AB≅BC Why?
We can prove it with the triangle congruent theorem, postulate side-side-angle
We are watching triangle ΔABO and triangle ΔCBO, they are congruent
first element side OB=OB - common side
second element side OA=OC=r - radius of the circle
third element angle ∡ABO≅∡CBO=90°
According to the postulate side-side-angle we can conclude that triangles
ΔABO≅ΔCBO (triangles are congruent)
If they are congruent all of their elements are also congruent and therefore also
side AB=BC => AB+BC=AC, which is chord => 7.6+7.6=15.2 units
AC= 15.2 units ( chord )
Good luck!!!

Answer:
y = - 
x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = 
= 
= -
The line crosses the y- axis at (0, 2) ⇒ c = 2
y = - x + 2 ← equation of line
