Answer:

1) 102

2) x = 31°; y = 6

3) m = 28°, n = 31°

4) x = 79°

Step-by-step explanation:

1) Angle ABD = 180 - 2(69) = 42

Angle DBC = 180/3 = 60

Angle ABC = 42 + 60 = 102

2) Angle ABC = 180 - 2(59) = 62

x = 62/2

x = 31°

ABD and CBD are congruent triangles so y = 6

3) 118 = m + 90

Exterior angle = sum of interior angles

m = 118 - 90 = 28°

n = (180-118)/2 = 31°

4) x = (180-22)/2 = 79°

Virty [35]

3x + xy^2 + 5x - 2xy ok so once you can decode the sentence this is what it will look like. First you add the common facts which are 3x and 5x which = 8x ok so now we have 8x + xy^2 - 2xy so then I believe you cant do anything after that because there will be no more common factors hey can you tell me if I am write if you have already had turn this in please hope this helps

What is the value of k if 2x^3-3x^2+kx-4 is divided by x-3 and gives a remainder of -7?

Alik [6]

By the polynomial remainder theorem, the remainder upon dividing a polynomial $p(x)$ by $x-c$ is the same as the value of $p(c)$ .
