I need step by step explanation and answer please

Mathematics
1 answer:
fredd [130]3 years ago
7 0

Answer:

2

Step-by-step explanation:

Trigonometric identities:

\sin^{2} (x)  +  { \cos}^{2} (x) = 1 \\  {\cos}^{2} (x) = 1 -  { \sin}^{2} (x) \\   { \sin }^{2} x = 1 - {\cos}^{2} (x) \:

Replace into the equation

\frac{ \sqrt{1 -  \cos^{2} (x) } }{ \sin(x) }  +  \frac{ \sqrt{1 -  \sin^{2}(x) } }{ \cos(x) }   \\ \\   =  \frac{ \sqrt{ \sin^{2}(x) } }{ \sin(x) }  +  \frac{ \sqrt{ \cos^{2}(x) } }{ \cos(x) }

Remove roots and simply

=  \frac{ \sin(x) }{ \sin(x) }  +   \frac{ \cos(x) }{ \cos(x) }  \\  \\  = 1 + 1 \\  = 2

Aloiza [94]

Answer:

136 m2 Option c

Step-by-step explanation:

136 m2

1 base = 6 × 7 = 42

2 sides = 2(7 × 5) = 70

2 triangles = 2(6 × 4

2

) = 24

SA = 42 + 70 + 24 = 136 m2

1) y=7x- 12<br>-3x+4y=2​
ioda

Answer:

x = 2

y = 2

Step-by-step explanation:

Given that:

y=7x- 12  -------- eq1

-3x+4y=2​ ------ eq2

eq1 can be written as:

7x - y = 12

Multiplying this equation by 4 we get:

28x - 4y = 48 --------- eq3

Adding eq2 and eq3 we get:

28x - 3x = 48+ 2

25x = 50

x = 2

Now put this equation in eq1

y = 7(2) - 12

y = 14 - 12

y = 2

i hope it will help you!
