The length of guy wire needed to make an angle of 30° with the ground is 310 feet. The angle between the end of the shadow and the vertical side of the building is 23°
<h3>What is
trigonometric ratio?</h3>
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
a) Let l represent the length of the guy wire.
sin(30) = (170 - 15) / l
l = 310 feet
b) Let Ф represent the angle, hence:
tanФ = 100/230
Ф = 23°

F = (-3,3)
scale factor of 10
-3 * 10 = -30
3 * 10 = 30
answer : (-30,30)
Answer:
100 / 112
Step-by-step explanation:
100 miniuts is a part of 112 adn is not a fraction and it does not say to siplify so you should be good.
(a) There are 1/4 cups of flour per serving
<u>Work:</u> 1.5/6=1/4
(b) There are aprox. .18 cups of sugar per serving.
<u>Work:</u> 9/12+4/12=13/12 n then divide 13/12 by 6
(c) You need 2 1/4 cups of flour to make 9 servings
<u>Work:</u> 1.5/2=.75 1.5+.75=2.25=2 1/4 cups
(d) Someone would need to know the amount of sugar per serving to make the recipe accurate.
<em>Question 2</em>
(a) You're account is at $10 dollars
<u>Work:</u> $5x5 (days)=$25. add 25 to -15 and you have $10 dollars in you're account.
(b) 5 days.
<u>Work:</u> 10/2=5 10-10=$0
