Help due today please

Answer:

angle ABD =55 degree

angle BCD= 125 degree

Step-by-step explanation:

angle ABD and angle DBC are supplementary angles.

Hence, angle ABD +angle DBC = 180 --equation 1

angle ABD = (2x+15) ---equation 2

angle BCD = (4x+45) ------equation 3

ABD+DBC=180

(2x+15) + ( 4x+45 ) = 180

2x+4x+15+45=180

6x+60=180

6x=180-60

6x=120

x=120/6=20

angle ABD= 2x+15= 2(20) +15

=40+15= 55 degree

angle BCD= 4x+45 = 4(20) +45

= 80+45= 125 degree

Hence, angle ABD =55 degree

angle BCD= 125 degree

Hope this helps.

For a regular 30-sided polygon, what is the degree of rotation? enter your answer in the box. °

Crank

For a 30 sided regular polygon, We can divide the polygon (30 sides) into 30 inscribed triangles with central vertex angles of = $\frac{360}{30} =12^{o}$ .

This central vertex angle of 12 degrees is the degree of rotation for a 30 sided polygon.

In other words, the 30 sided polygon has 12 degree rotational symmetry about the center.

write an equation of the line that's passes through the point (1,6) and is parallel to the line whose equation is y= 3x - 5

Alex Ar [27]

Parallel lines have the same slope.
so to find any line, you need a set of points, and a slope.
we already have the slope, being 3.
so, use the equation
y- (y-point)/ x-(x-point)=slope.
y-6. 3
---- = ---- (make it a fraction by puttingitover 1)
x-1. 1
cross multiply.
1(y-6)=3 (x-1)
y-6=3x-3
add 6 to both sides
Final answer: Y=3x+3
