Question 6 (1 point)

Mathematics
1 answer:
nikklg [1K]3 years ago
5 0

Answer:

y=-8 and x =3

Step-by-step explanation:

4x - y = 20 and -2x - 2y = 10

if we multiply the second equation by -2 we have:

4x + 4y = -20 and 4x - y = 20

we subtract the two equations and we have

5y = -40 so y=-8 which means x= 3

What is the value of x in the triangle?
Arturiano [62]
We can use SOH CAH TOA to solve this :)

We’re going to use Cosine because the angle and sides given are Adjacent and Hypotenuse- which goes with the CAH part of SOH CAH TOA.

Cos(18) = x/25

Multiply both sides by 25

25cos(18) = X = 23.776

So x = 23.776 cm

I hope this Helps!
