Answer:
Step-by-step explanation:
By adjacent interior angles theorem,
If a transversal line 'r' intersects two parallel lines 'm' and 'n' then the consecutive interior angles are supplementary.
a° + (3x - 18)° = 180°
a° = 180° - (3x - 18)°
By vertical angles theorem,
If two straight lines intersect each other at a point, opposite angles formed are equal in measure.
180° - (3x - 18)° = (5x - 10)°
(5x - 10) + (3x - 18) = 180
(5x + 3x) - (10 + 18) = 180
8x - 28 = 180
8x = 180 + 28
8x = 208
x = 26

Answer:
For this equation to be true, a must = 13 and b must = 10 + 2i.
Step-by-step explanation:
First combine the numerators: 3 + 5 + 2i + 2, or 10 + 2i.
Next, multiply the denominators: 4 + 9 = 13
Then rewrite the original equation as:
10 + 2i a
---------- * ---- = 1
13 b
For this equation to be true, a must = 13 and b must = 10 + 2i.
Answer:
a) The radius of the wheel is 1) more than 25.0 cm.
b) The radius of the wheel is approximately 40.925556... cm
Step-by-step explanation:
S = rθ is the formula to find the radius of the wheel using the arc and the angle discovered, S being the arc and θ the angle. The angle, however, must be in radians. θ =
is used to convert it. So:
θ = 
θ = 
S = rθ
25 = r 
900 = 7
r
r = 
r = 40.925556... cm
