For the answer to the question above, \
Let
D = Dominic weight
R = Ralph weight
P = Peter weight
We have three unknowns so we should set up three equations. We do as follows:
D = 0.5R
P = 3D
D+R+P = 720
Solving simultaneously we obtain,
D = 120
R = 240
P = 360
<span>So the answer is 120 is the weight of Dominic</span>
Each side is equal so you divide 100 by 4.
Answer is: 25 m
10^2 - 8^2
= 100 - 64
= 36
LM = √36 = 6
answer
LM = 6
Answer:
54.8 feet
Step-by-step explanation:
We assume that the distance of interest is the direct line distance from the observation point to the bottom of the monument, segment PH in the diagram below.
This can be found using the Law of Sines.
∠PMH is the complement of the angle of elevation to the top of the monument, so is 40°.
∠MPH is the difference in the angles of elevation, so is 28°.
__
The Law of Sines tells us the ratio of side lengths is the same as the ratio of the sines of the opposite angles, so ...
PH/MH = sin(∠PMH)/sin(∠MPH) = sin(40°)/sin(28°)
Multiplying by MH, we can find the length of PH:
PH = (40 ft)(sin(40°)/sin(28°)) ≈ 54.7669 ft
PH ≈ 54.8 ft . . . . the distance Pete must climb to reach the monument.
