Answer:
33 + 6 i
Step-by-step explanation:
3 * i * (2 - (11 * i)) =
To answer the given question, substitute the values given to the equation,
S = π x sqrt(r² + h²)
155 m = π x sqrt (r² + (21 m)²))
r = 44.65 m
Therefore, the radius of the cone is approximately 44.65 m.
Find the constant of proportionality
Answer:
x = 4
Step-by-step explanation:
since it is an equilateral triangle, each angle is 60°. To find x, set up the equation 17x-8=60
17x = 68
x=4
9514 1404 393
Answer:
Step-by-step explanation:
Angles A and P are marked congruent; angles B and Q are marked congruent, so the triangles are similar by the AA similarity postulate. The similarity statement can be written ...
ΔABC ~ ΔPQR by AA similarity
__
The ratio of sides of PQR to ABC is the ratio QR/BC = 12/6 = 2. That is, each side in the larger triangle is 2 times the length of the corresponding smaller side.
PQ = 2·AB = 2·4 = 8
PR = 2·AC = 2·7 = 14
The side lengths of interest are ...
PQ = 8, PR = 14
