A=2 b=2 c=1 Find the value of 2abcosC

mel-nik [20]

Answer:

$2abCosC = 1$

Step-by-step explanation:

The cosine rule is

=> $a^2= b^2+c^2-2abCosC$

For 2abCosC, it becomes

=> $2abCosC = b^2+c^2-a^2$

=> $2abCosC = (2)^2+(1)^2-(2)^2$

=> $2abCosC = 1$

Please helppp (had to have 20 words haha)

Answer:

w==77

Step-by-step explanation:

The sum of the 2 opposite interior angles equals the exterior angle.

w-36 +w-20=w+21

combine like terms: 2w-56=w+21

subtract w from both sides: w-56=21

add 56 to both sides: w=77

Jonah has collected 91 coins worth $7.20 in his piggy bank. his collection includes only dimes and nickels. how many dimes are t

deff fn [24]

There are 53 dimes in Jonahs piggy bank. You must use algebra to solve for a variable X as follows: x.10+(91-X).05=7.2 Solving through will yield X =53 which means 91 - 53 = 38. 53*.10 + 38*.05 = $7.20. Other methods will also work, but this is the most straight forward.
