Help, please!! What is mA?
Inga [223]

Answer:

38°

Step-by-step explanation:

The measure of required angle can be obtained by using cosine law.

From the given triangle we find that:

a = 5, b = 3, c = 7,

Since,

cos (A) = (b^2 +c^2 - a^2) /2bc

Therefore,

cos (A) = (3^2 + 7^2 - 5^2) /(2*3*7)

cos (A) = (9 + 49 - 25) /(42)

cos (A) = (33) /(42)

cos (A) = 0.785714286

A = arccos(0.785714286)

A = 38.213210675°

A = 38°

a washer and dryer cost $586 combined. the washer costs $64 less than the dryer. what is the cost of the dryer?
oksano4ka [1.4K]
Hello!

*I'm not very good at algebra, so I am not 100% sure this is correct!*

w = cost of washer

d = cost of dryer

w + d = $586

w = d - 64

d - 64 + d = 586

2d = 586 + 64

2d = 650

d = 650 / 2 = 325

586 - 325 = 261

Check 325 - 261 = 64

So, the dryer costs $325 and because the washer is $64 less than the dryer, it costs $261.
