Sine law to find angle R
All angles in triangle add to 180 so we can find angle P
P = 180 - R - Q
P = 180 - 35.7899447211 - 64
P = 80.2100552789
sine law with angle P to find length of RQ
or use cosine law
either way the answer is 205.57 feet
Answer:
B. RY/RS=RX/RT=XY/TS
Step-by-step explanation:
In the picture attached, △RST and △RYX (which are similar) are shown
The options are:
Given that the triangles are similar, then their sides are proportional. Then, there is some constant k, which satisfies:
k*RS = RY
k*RT = RX
k*TS = XY
This can be rewritten as:
k = RY/RS = RX/RT = XY/TS
Answer:
22cm
Step-by-step explanation:
Circumference of a circle = 2πr
π = 22/7
r = 3.5
Circumference of a circle = 2 × (22/7) × 3.5
Circumference of a circle = 22cm.
<h2>
The value of A/b is 2.60</h2>
Step-by-step explanation:
We have cosine formula
c² = a² + b² - 2ab cosC
Here
c = B
a = 6
b = 7
C = 60°
Substituting
B² = 6² + 7² - 2 x 6 x 7 cos60
B² = 43
B = 6.56
b = 7 closest integer to B.
Given that A is area of triangle
A=0.5absinC
A = 0.5 x 6 x 7 x sin60 = 18.19
We need to find
The value of A/b is 2.60
