Answer:
x = 12 degree
Step-by-step explanation:
3x + 19 + 5x = 115 degree (sum of two interior opposite angles are equal to the third side)
8x + 19 = 115
8x = 115 - 19
x = 96 /8
x = 12
Multiply it out, 6v+ 6*4 = final answer. 6v+24
Answer:
-24/5
Step-by-step explanation:
The solution to the problem is as follows:
cscx < 0 means 1/sinx < 0, or sinx < 0.
sinx = -3/5 because you're dealing with a 3-4-5 triangle, and we established
sinx is negative.
sin2x = 2sinxcosx = 2*-3/5*4/5 = -24/25
cos(2x) = cos^2(x) - sin^2(x) = 16/25 - 9/25 = 5/25 = 1/5
tan2x = sin2x / cos2x = -24/5
