Find the angle measurements and side lengths for the triangle below

Mathematics
1 answer:
rewona [7]2 years ago
4 0

Answer:

Step-by-step explanation:

Sin(A) = 5/7

Sin(A) = 0.7143

A = sin-1(0.7143

A = 45.58

B = 180 - 45.58 - 90

B =  44.43

C = 90

c = 7

a = 5

b^2 = c^2 - a^2

b^2 = 7^2 - 5^2

b^2 = 49 - 25

b^2 = 24

b = 4.899

What is a real life example of trigonometric ratios
Brut [27]

Answer:

Trigonometry can be used to measure the height of a building or mountains

Step-by-step explanation:

if you know the distance from where you observe the building and the angle of elevation you can easily find the height of the building. Similarly, if you have the value of one side and the angle of depression from the top of the building you can find and another side in the triangle, all you need to know is one side and angle of the triangle.

Cristina bought a bag of coffee for $8.47. The weight of the bag was 7/8 of a pound. What was the price, per pound, of the coffe
SpyIntel [72]
~For this problem, you need to divide. 
~The easy way that I think might help you is if you change the fraction into a decimal. 
 
\frac{7}{8} = 0.875
  
Now divide $8.47 by 0.875
\frac{8.47}{0.875} = 9.68
     
     The price per pound of the coffee was $9.68

Slope -1 passes through (7,2)
kvv77 [185]
Y = mx + b
slope(m) = -1
(7,2)...x = 7 and y = 2
now we sub and find b, the y int
2 = -1(7) + b
2 = -7 + b
2 + 7 = b
9 = b

so ur equation of this line is : y = -1x + 9.....can also be written as :
y = -x + 9....or if u need it in standard form, it is : x + y = 9
