Given sec (theta) = 3 what is the exact value of csc (90 - (theta))

sp2606 [1]

Sec θ = 3
1/cos θ = 3
cos θ = 1/3

csc (90 - θ) = 1/sin (90 - θ) = 1/cos θ = 1/(1/3) = 3

Therefore, csc (90 - θ) = 3.

Please. <br><br>Find BC. If AB = x, BC = 8x-4 and AC =77°.<br>

Xelga [282]

Answer:

91 1/9

Step-by-step explanation:

Because this is clearly a triangle, the total number of degrees all the angles add up to is 180 degrees. In this scenario, we have $x+(8x-4)+77=180$

Combining like terms, we have $9x-4+77=180$

Combining like terms again, we have $9x+73=180$

Subtracting 73 on both sides, we have $107=9x$

Dividing by 9 on both sides, we have $x = 11 \frac{8}{9}$

Plugging back into BC = 8x - 4, we have $\frac{856}{9} - 4$

Combining like terms, we have $\frac{820}{9}$ , which is $91 \frac{1}{9}$
