Find value of x Find value of y

Mathematics
1 answer:
Softa [21]2 years ago
4 0

Answer:

Step-by-step explanation:

use  SOH CAH TOA

Sin = Opp / Hyp

Cos = Adj / Hyp

Tan = Opp / Adj

then we know the adjacent side and the angle, and want to find the Hyp, so use  CAH

Cos(60) = ( 8\sqrt{3}  / 3 ) / Hyp       ( cos(60) = 1/2 )

Hyp = (8\sqrt{3} / 3) / (1/2)

Hyp = 2 ((8\sqrt{3} / 3)

Hyp = 16\sqrt{3} / 3

x =  16\sqrt{3} / 3

Now use SOH

Sin (60) = Opp / 16\sqrt{3} / 3      ( sin(60) = \sqrt{3}/2 )

(16\sqrt{3} / 3)(\sqrt{3}/2) = Opp

16 * 3 / 6  = Opp

8 = Opp

y = 8

stiks02 [169]

Answer:

35.6 yd²

Step-by-step explanation:

Area of ∆UVW can be solved if we know the lengths of 2 sides and their included angle.

We are Given just 1 side, UV (w). Use the law of sines to find UW (v).

Thus:

\frac{v}{sin(V)} = \frac{w}{sin(W)}

W = 137°

w = 19 yd

V = 180 - (137 + 22) = 21°  => sum of triangle

v = ??

Plug in the values and solve for v

\frac{v}{sin(21)} = \frac{19}{sin(137)}

Multiply both sides by sin(21)

\frac{v}{sin(21)}*sin(21) = \frac{19}{sin(137)}*sin(21)

v = \frac{19*sin(21)}{sin(137)}

v = 10 yd (approximated)

Find area of ∆UVW:

Area = ½*UV*UW*sin(U)

Area = ½*v*w*sin(U)

= ½*10*19*sin(22)

Area = 35.6 yd² (to nearest tenth)

The total number of victories for a football team exceeds the number of defeats by 4, with no draws. Knowing that if 44 jojos, h
Leno4ka [110]

Answer: 24

Step-by-step explanation:

Let the number of defeats be represented by x.

Since the total number of victories exceeds the number of defeats by 4, then the number of victories will be:

= x + 4

We then add the number of victories and losses together and equate them to 44. This will be:

x + x + 4 = 44

2x + 4 = 44

2x = 44 - 4

2x = 40

x = 40/2

x = 20

Therefore number of victories will be:

= x + 4

= 20 + 4

= 24
