14 x 12 = 168
168 divded by 2.90 = 57.9
Answer:
m∠ADC = 132°
Step-by-step explanation:
From the figure attached,
By applying sine rule in ΔABD,
sin(∠ADB) =
= 0.74231
m∠ADB =
= 47.92°
≈ 48°
m∠ADC + m∠ADB = 180° [Linear pair of angles]
m∠ADC + 48° = 180°
m∠ADC = 180° - 48°
m∠ADC = 132°
Answer:
Step-by-step explanation:
<u>Area of the regular polygon:</u>
- A = Pa, where P- perimeter, a- apothem
a. <u>Side length is:</u>
- s/2 = √13²-12² = √25 = 5
- s = 10 units
<u>Perimeter is:</u>
b. <u>Area is:</u>
Answer:
18.2
Step-by-step explanation:
because 17+24+19+17+14=91 then 91/how ever many numbers are in the equation not including the answer is what what you divide by in this case it is 5 so 91/5 is 18.2
Hope this helped!!
Answer:
Step-by-step explanation:
30w-w-6-5w-4=-5w-6-8+3w
30w-w-4=-8+3w
29w-4=-8+3w
29w-3w=-8+4
26w=-8+4
26w=-4(divide bother side by 26)
w=-2/13
