Answer:
Step-by-step explanation:
given that You are visiting a Redwood tree forest and want to verify the height of one of the trees. You measure its shadow along the ground and use trig to calculate the height.
the shadow measures 500 feet and you calculate the angle of elevation to be 35 degrees, This forms a right triangle.
a) Other acute angle is 90-35 = 55 degrees
b) Height of the tree = 500 tan 35 =350.104 feet
c) Here height would be reduced to 350.104 - 5 = 345.104 feet.
Hence distance adjusted= 354.104 cot 35=492.8596 feet.
d) Yes because this is less than 500 feet.
e) height of 5 feet itself is sufficient here
Is this correct on what you typed above ->
Answer:
8/9 (simplified)
Step-by-step explanation:
Total marbles = 18
Total of marbles <em>not</em> white = 16
Numerator = 16 / Denominator = 18
= 16/18
= 8/9 (simplified)
Multiply the numerators: 7×8=56 then the denominators 10×21=210. The lowest multiples for 56 and 210 is 14. So divide 56/14=4 and 210/14=15. Your answer is 4/15.
Hope this helps (:
The area of one window is 15 ft²
Step-by-step explanation:
Area of a trapezoid window can be calculated as ;
1/2(a+b) h where
a=outside edge length
b=inside edge length
h=length across
Given that ;
a=1 ft
b=5 ft
h=5 ft
Area= 1/2( 1+5)5
Area= 1/2 (6)5
Area=3*5 =15 ft²
