2(21x − 7) + 4(3x + 2) = 6(2x + 9) + 3
42x - 14 + 12x + 8= 12x + 54 + 3
54x - 6= 12x + 57
54x=12x + 63
42x=63
x= 63/42
x= 3/2

Can anyone help me on this? I need an exact answer please no guesses

x = 32°

The triangle has 2 equal sides and is therefore isosceles, thus the 2 base angles are also congruent.

The 2 base angles are of size x°

x = $\frac{180 - 116}{2}$ = $\frac{64}{2}$ = 32

During a free fall Swati was accelerating at -9.8m/s^2. After 120 seconds how far did she travel? Use the formula =1/2 * t^2 to

jarptica [38.1K]

Answer:

She traveled 70560 m.

Step-by-step explanation:

Given :

Acceleration (g) = $-9.8m/s^{2}$

Time : 120 seconds .

To Find : Distance traveled

Solution:

Since we are given that there is a free fall .

So, we will use the formula: $d=\frac{1}{2} gt^{2}$

Now put the given values in the formula :

⇒ $d=\frac{1}{2}*(-9.8)*(120)^{2}$

⇒ $d=\frac{1}{2}*(-9.8)*14400$

⇒ $d=\frac{-141120}{2}$

⇒ $d=-70560$

Negative sign shows the direction only.

Hence she traveled 70560 m.
