Solve the triangle: α = 40°, β = 35°, and a = 10.
luda_lava [24]

The triangle: α = 40°, β = 35°, and a = 10. is b = 8.9, γ = 105°, c = 15.0

<h3 /><h3>What is Sine Law?</h3>

If A, B, and C are the measurements of the angles of an oblique triangle, and a, b, and c are the lengths of the sides opposite of the corresponding angles, then the ratios of the a side’s length to the sine of the angle opposite the side must all be the same.

a/ sin A = b/ sin B = c/ sin C

Using Angle sum property in a triangle we have,

α+β+ γ = 180

40+35+ γ=180

γ= 180-75

γ= 105°

Now,

c/ sin γ= a/ sin α

c/ sin 105= 10/ sin 40

c/ 0.96592 = 10 /0.6427

c = 15

again,

b/ sin  β=  a/ sin α

b/ sin 35=  10/ sin 40

b/0.5737= 15.559

b= 8.92

Answer:

1 plain pizza costs $10.50 and 1 pepperoni pizza costs $12.50

Step-by-step explanation:

Jack: 3x+2y= 58.5

Jill:    2x+4y=67

a) Multiply both equations so that one of the coefficients (number before the letter) are equal:

6x+4y=117

6x+12y=201

b) We can now easily subtract them to get:

(subtracted 6x) 4y=117  12y=201 (12y-4y and 201-117 next) 8y=84

c) Now we can divide 84 by 8 to get y=10.5, so now we can substitute it into any of the equations:

2x+(4*10.5)=67 --> 2x+42=67 -(subtract 42 from both sides)-> 2x=25  -(divide both side by 2)-> x=12.5.

d) To check if it works: 2(12.5)+4(10.5)=67 25+42=67 so it's correct.
