I believe that it will equal a-7 because the 2 cancels out with the -9 below making it -7 but I don't know it is still in a fraction of not sorry about that part hope this helps you somewhat

The triangle shown is a right triangle. Create the equation to be used to find the missing lengths.

telo118 [61]

The equation used to find the missing lengths:
9 = __SR (5^2 + x^2)__
As long as it is a right triangle, this is called the Pythagorean Theorem
${9}^{2} = {x}^{2} + {5}^{2} \\ \sqrt{ {9}^{2} } = \sqrt{( {x}^{2} + {5}^{2} )} \\ 9= \sqrt{( {x}^{2} + {5}^{2} )}$

** FYI- if you wanted to SOLVE FOR THE MISSING SIDE X, then just switch around the original equation solving in terms of x:
${9}^{2} = {x}^{2} + {5}^{2} \\ {x}^{2} = {9}^{2} - {5}^{2} \\ x= \sqrt{( {9}^{2} - {5}^{2})} = \sqrt{(81 - 25)} \\$
$x = \sqrt{56} = \sqrt{(8 \times 7)} \\ x= \sqrt{(4 \times 14)} = \sqrt{4}\times \sqrt{14} \\ x = 2 \sqrt{14}$

Please I need the answer very fast

Answer:

1 - cosΘ

Step-by-step explanation:

using the identity

sin²x + cos²x = 1 , then

sin²x = 1 - cos²x

$\frac{sin^20}{1+cos0}$

= $\frac{1-cos^20}{1+cos0}$ ← factor 1 - cos²Θ as a difference of squares

= $\frac{(1-cos0)(1+cos0)}{1+cos0}$ ← cancel 1 + cosΘ on numerator/ denominator

= 1 - cosΘ

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.

Part A: The answer is B.
As vertically opposite angles are equal
x+10=4x-35
10=3x-35
45=3x
x=15

Part B: The answer is D.
We'll substitute in the value of X in one equation.
x+10
=15+10
=25
As the two angles are equal bot must be 25 degrees.
