Answer:
The distance between Tyrone and the piano is 23.7 yards
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the measure of angle P
Remember that the sum of the internal angles of a triangle must be equal to 180 degrees
∠T+∠D+∠P=180°
substitute the given values
65°+77°+∠P=180°
142°+∠P=180°
∠P=180°-142°=38°
step 2
applying the law of sines
substitute the given values
therefore
The distance between Tyrone and the piano is 23.7 yards
The following triangle is a scalene triangle
180 - x = r is true.
Thats the only one which is true.
Answer:
(1) 13.0 years
(2) {-1728, 1728}
Step-by-step explanation:
(1)
Compound annually:
= A
(47000) = 79200
=
ln() = ln()
ln and e cancel out.
(0.04)(t) = ln()
t =
t = 13.0 years
(2)
Substitute y with -4x.
Solve for x.
x = {-3, 3}
Plug in x values into any equation to find y.
y = -4(-3) and y = -4(3)
y = {-12, 12}
= = -1728
= = 1728
Answer:
i would go with the third option. III, II, I, IV
Step-by-step explanation:
Draw a line connecting the point to the center of the circle.
Construct the perpendicular bisector of that line.
Place the compass on the midpoint, adjust its length to reach the end point, and draw an arc across the circle.
Where the arc crosses the circle will be the tangent points.
