Answer:
Step-by-step explanation:
a^2+6^2 = 23^2
a^2 = 23^2 - 6^2
a^2 = 529 - 36
a^2 = 493
a = √493
a = 22,20
Answer: (<em>Draw a circle and a point outside the circle.)</em>
Step-by-step explanation:
Step 1: Draw a circle and a point outside the circle.
Step 2: Draw line OP, to join the center O to point P.
Step 3: Construct the perpendicular bisector of OP.
Step 4: Draw two arcs on the circumference of the circle.
Step 5: Draw tangent lines JP and KP.
Proof:
11x = 2y - 5
11x + 5 = 2y
2y = 11x + 5 (<u>a</u>x + b form)
y = (11x + 5)/2
y = 11x/2 + 5/2
The slope is <u>11/2</u>
Answer:
x = 9 Angle B = 40 degrees
Step-by-step explanation:
Angles A and B are congruent, so the equation are the same
5x - 5 = 3x + 13
-3x - 3x Subtract 3x from both sides
2x - 5 = 13
+ 5 +5 Add 5 to both sides
2x = 18 Divide both sides by 2
x = 9
Plug this into the equation for angle B
B = 3(9) + 13 Multiply
B = 27 + 13 Add
B = 40
