How to find the measure of angle FGC If segments AC and BD are parallel and they are cut by the transversal FE

1 answer:

6 0

Angles FGC and FHD are equal by the Corresponding Angles Theorem.

Make them equal to each other in an equation.
3x - 9 = 2x + 1
Add 9 to both sides.

3x = 2x + 10
Subtract 2x from both sides.

x = 10

Plug in 10 for x in the expression for angle FGC, 3x - 9.
3(10) - 9
30 - 9 = 21

∠FGC = 21°.

Determine the zeros of the expression -16t^2-8t+24.

Lina20 [59]

$-16t^2-8t+24=-8(2t^2+t-3)=-8(2t^2+3t-2t-3)\\\\=-8[t(2t+3)-1(2t+3)]=-8(2t+3)(t-1)\\\\\text{the zeros}\\\\2t+3=0\to t=-1.5\\t-1=0\to t=1\\\\Answer:\ \boxed{-1.5\ and\ 1}$
