BDC=95
Answer:
[tex] m\angle BDC = 95\degree [/tex]
Step-by-step explanation:
[tex] In\: \triangle ACD\: \&\:\triangle BDC[/tex]
[tex] m\angle A = m\angle B[/tex] (given)
[tex]\because m\angle A = 50\degree [/tex]
[tex]\therefore m\angle B = 50\degree [/tex]
[tex] m\angle ADC = m\angle BCD[/tex] (given)
[tex]\because m\angle ADC = 35\degree [/tex]
[tex]\therefore m\angle BCD= 35\degree [/tex]
[tex] In\: \triangle BDC[/tex]
[tex] m\angle BDC = 180\degree - (m\angle B+m\angle BCD) [/tex]
(By angle sum postulate of a triangle)
[tex] m\angle BDC = 180\degree - (50\degree +35\degree ) [/tex]
[tex] m\angle BDC = 180\degree - (50\degree +35\degree ) [/tex]
[tex] m\angle BDC = 180\degree - 85\degree [/tex]
[tex] m\angle BDC = 95\degree [/tex]

Hope this helps you!!!
The equation x² - 4 = 0 and 4x² = 16 have roots of x = -2 and 2 so option 1st and 4th are correct.
What are the roots of an equation?Roots of an equation are the solution of that equation, since an equation consists of hidden values of the variable so to determine them by different processes and then the resultant is called roots.
For example root of x -4 = 0 is x = 4 so 4 will be the only root of this linear equation.
The number of roots of an equation depends on the degree of the equation for example number of roots of quadratic equation are 2.
Given the roots
01)
x = -2
square both sides
x² = 4
x² - 4 = 0
02)
x = 2
Square both sides
x² = 4
Multiply by 4 on each side
4x² = 16
Hence "The equation x² - 4 = 0 and 4x² = 16 have roots of x = -2 and 2".

Three interior angles of a polygon are 125,140 and 160. The remain angles are 145 each. Calculate the sum of the interior angles of the polygon
Answers
Answer:
1440 degrees.
Step-by-step explanation:
125 + 140 + 160 = 425 degrees.
The remaining angles are each 145.
The exterior angles of all polygons sum to 360 .
So we have exterior angles sum of the 3 given angles
= (180-125) + ( 180-140) + (180-160)
= 55 + 40 + 20 = 115.
So the remaining vale of the sum is 360 - 115
= 245 degrees.
An internal angle of 145 will give an external one of 35 degrees.
245/35 = 7.
So there are 7 145 degree angles in the polygon.
Sum of the interior angles is therefore:
425 + 7*145
= 1440 degrees.
This is a 10 sides polygon ( a decagon).
