Answer:
5 = side a
3 = side c
angle B = 62 degrees
JK is side b
Use the Law of Cosines to find the length of side b.
b^2 = a^2 + c^2 − 2ac cos(B)
b^2 = (5^2 + 3^2) − ( 2 x 5 x 3) cos(62°)
b^2 = (25 + 9) − 30 x 0.469
b^2 = 34 - 30 x 0.469
b^2 = 34 - 14.084
b^2 = 19.916
b = √19.916
b = 4.463
Rounded to the nearest tenth is 4.5 mm.

Answer:
x = 25
Step-by-step explanation:
The Exterior Angle Theorem states that the exterior angle of a triangle is equal to the sum of the two opposite interior angles.
This means that
3x - 10 = 25 + (x+15)
3x - 10 = x + 40
Subtract x from both sides of the equation.
2x - 10 = 40
Add 10 to both sides.
2x = 50
Divide both sides by 2.
x = 25
Answer:
Johnny wants to buy a game but he doesn't have enough money. He needs to have at most $60 to buy his game. He has $5 in his piggy bank and gets $11 for every hour for working. Write an inequality where x represents his hours.
11x + 5 ≤ 60
Not that good but its better than nothing.
Answer:
Substitute point (4, 8)
y = y1 + m(x - x1)
y = 8 + m(x - 4)
y = 8 + mx - 4m
let m = 3 (It can be anything) Substitute m into equation:
y = 8 + (3)x - 4(3)
y = 2x - 4
