Answer:
12
Step-by-step explanation:
g+I = 72
I * 5 = g
(I*5) + I = 72
6i = 72
I=72/6
I = 12
Answer:
The dimensions of the frame are 15 in x 13 in
Step-by-step explanation:
Let
x ----> the length of the picture
y ----> the width of the picture
we know that
-----> equation A
The area of the picture, including the frame is
so
----> equation B
substitute equation A in equation B
solve for y
solve the quadratic equation by graphing
The solution is y=7 in
see the attached figure
<em>Find the value of x</em>
Find the dimensions of the frame
therefore
The dimensions of the frame are 15 in x 13 in
Based on the information given, it has been calculated that they value of x will be 0.9646.
<h3>
Solving triangles</h3>
Based on the information given, it should be noted that the sine formula will be used.
Therefore, the equation to solve the question will be:
Sin 16° = x/3.5
x = Sin 16° × 3.5
x = 0.2756 × 3.5
x = 0.9646

The solution to 1 - cos(6x) is 2sin²(x).
Hence, option B) 2sin²(x) is the correct answer.
<h3>What is solution to 1 - cos(6x)?</h3>
Given that; 1 - cos(6x) = ?
First, we rewrite using trig identity
1 - cos(2 × 3x)
Using the double angle identity, { <em>cos2(x) = 1 - 2sin²(x)</em> }
1 - ( 1 - 2sin²(x) )
Eliminate the parentheses
1 - 1 + 2sin²(x)
2sin²(x)
The solution to 1 - cos(6x) is 2sin²(x).
Hence, option B) 2sin²(x) is the correct answer.
