Sine rule
a/Sin(A) = b/Sin(B) = c/Sin(C)
b
C / |
a / _| A
B c
We know that a = 70 degrees and A = 25 foot
So 70/Sin(25) = Something
We also know we want C, and that c = 90 degrees
So 70/Sin(25) = 90/Sin(C)
Then you have to rearrange the equations. Start with Multiply all by Sin(C)
So [Sin(C)][70/Sin(25)] = 90
Then divide everything by 70/Sin(25)
So Sin(C) = 90/[70/Sin(25)]
Now you want to isolate C, so Sin-1 everthing
So C = Sin-1{90/[70/Sin(25)]}
So C = 32.91309534
To the nearest tenth, 32.9ft
Hope that helps :)
Answer:
6x - 5 ≥ 8
Step-by-step explanation:
Which inequality corresponds to the sentence "five less than the product of a number and 6 is at least 8"?
The inequality sign of
a) At least = greater than or equal to = ≥
Let us represent the number as = x
Hence: "five less than the product of a number and 6 is at least 8" can be written as:
= x × 6 - 5 ≥ 8
= 6x - 5 ≥ 8
The new length of the string will be 16 1/4 feet. Then the correct option is B.
<h3>What is the length?</h3>
It is the measure of distance between the two points and is known as length. The length is measured in meters generally.
Ed needed to extend the string on his kite. The current string was seven and three-fourths feet that is (7 3/4).
The mixed fraction number is coverted into a decimal number.
7 3/4 = 7.75 feet
He cut a piece of string that measured 8.5 feet and added it to the existing string.
Then the new length of the string will be
L = 7.75 + 8.5
L = 16.25
L = 16 1/4 feet
The new length of the string will be 16 1/4 feet. Then the correct option is B.

Answer:
7/24
Step-by-step explanation:
1/8 + 1/6
First get a common denominator of 24
1/8 * 3/3 = 3/24
1/6 * 4/4 = 4/24
3/24 + 4/24 = 7/24
