Angle sum of a triangle = 180°
Type of Triangle: Isosceles.
Therefore, 2 of the angles are equivalent.
2x = 50
2 ( 25 ) = 50
50 = 50
Meaning that the sum of the 2 angles is 100°.
( 5y + 10 ) + 2x + 50 = 180
5y = 180 - 100 - 10
5y = 70
y = 70 / 5
y = 14°
ANSWER:
y = 14°
Answer:
n = 5
Step-by-step explanation:
3n + 8 = 23
- 8 - 8 Subtract 8 from both sides
3n = 15
n = 5 Divide both sides by 3
Answer:
y = 200·1.15^t
Step-by-step explanation:
The ratio from one year to the next is 1.15, so the balance is a geometric sequence. Since t starts at zero, we can write the balance (y) after t years as ...
Root of x = 4 means (x - 4) is a factorMultiplicity of two means that (x - 4) is used twice root of x= -4 means that (x+ 4) is a factormultiplicity of 1 means it is used once so y = a (x-4) (x-4) (x + 4)y = a (x^3 - 4x2 - 16x + 64)
Thus, any polynomial with these zeroans d as a minimum these multiplicities will be a multiple (scalar or polynomial) of this P(x).
