Keeping in mind that an isosceles triangle, has two equal sides, and those twin sides stemming out of the vertex, make up two twin angles at the base, since the sum of all interior angles in a triangle is 180°, thus 180° - 66° is 114°, and each angle at the base takes half of that, check the picture below.

Silas had 3 times as much money as Raja. Silas spent $84 of his money to buy a birthday gift for his grandma while Raja was awar
ella [17]

Answer:

Total money they had at first $252.

Step-by-step explanation:

Let,

x be the amount Silas had originally

y be the amount Raja had originally

According to given statement;

x = 3y     Eqn 1

x - 84 = y + 42    Eqn 2

Putting x=3y in Eqn 2

3y - 84 = y + 42

3y - y = 42 + 84

2y = 126

Dividing both sides by 2

\frac{2y}{2}=\frac{126}{2}\\y=63

Putting y = 63 in Eqn 1

x = 3(63)

x = 189

Total money they originally had = 189 + 63 = $252

Hence,

Total money they had at first $252.

If 2 - 3i is a solution to the equation x3 - 3x2 + 9x + 13 = 0, what are the other roots of the equation?
OLga [1]
The complex solutions come in pairs and the only difference between them is the sign between the real and imaginary part, so one of the other two solutions is 2+3i. The third solution can be easily found using the rational root theorem, and it's equal to -1.

Anarel [89]

Answer:

The slope of the line is -7/8

When the point (7, –4) is used, the point-slope form of the line is

y+4=(-7/8)(x-7)

The slope-intercept form of the line is y=(-7/8)x+(17/8)
