Answer:

1-cos2A/sin2A

=(1-cos^2 A+sin^2 A)/(2sinAcosA)

=(sin^2 A+sin^2A)/2sinAcosA

=2sin^2 A/2sinAcos^2 A

=sinA/cosA

Quesheip Use the number line below, where RS = 6y +2, ST=5y + 9, and RT= 13y - 1 a What is the value of y? b Find RS, ST, and RT

Simora [160]

Answer:

$y = 6$

$RS = 38$

$ST = 39$

$RT = 77$

Step-by-step explanation:

Given:

$RS = 6y +2$

$ST=5y + 9$

$RT= 13y - 1$

Solving (a): The value of y

From the given parameters, we understand that

$RT = RS + ST$

Substitute values for RS, ST and RT

$13y - 1 = 6y + 2 + 5y + 9$

Collect Like Terms

$13y - 6y - 5y = 1 + 2 + 9$

$2y = 12$

Divide both sides by 2

$y = \frac{12}{2}$

$y = 6$

Solving (b):

<em>The value of RS</em>

Substitute 6 for y in $RS = 6y +2$

$RS = 6 * 6 + 2$

$RS = 36 + 2$

$RS = 38$

<em>The value of ST</em>

Substitute 6 for y in $ST=5y + 9$

$ST = 5 * 6 + 9$

$ST = 30 + 9$

$ST = 39$

<em>The value of ST</em>

Substitute 6 for y in $RT= 13y - 1$

$RT = 13 * 6 - 1$

$RT = 78 - 1$

$RT = 77$

Find the missing side length in the image attached.

Aleks [24]

Answer:

? = 56.

Step-by-step explanation:

In the problem, the side 20 corresponds to side 32 and side 20 + 35 corresponds to side 32 + ?.

$\frac{20}{32} =\frac{20 + 35}{? + 32}$

$\frac{5}{8} =\frac{55}{? + 32}$

$\frac{1}{8}=\frac{11}{? + 32}$

? + 32 = 8 * 11

? + 32 = 88

? = 56.

Hope this helps!
