Answer:
By the definition of midpoints, AX and CX are congruent. By the definition of segment bisectors, X is the midpoint of BD, and therefore BX and DX are congruent. Since angle AXD and CXB are vertical angles, they are congruent by the vertical angles theorem. By SAS, triangles AXD and CXB are congruent. By CPCTC, angles A and C are congruent. By converse of alternate interior angles theorem, AD is parallel to CB.
Y + 2x = 3....put this in y = mx + b form by subtracting 2x from both sides
y = -2x + 3
so u have a slope of -2 and a y int of 3 or (0,3)
ur x int can be found by subbing in 0 for y and solving for x
y + 2x = 3
0 + 2x = 3
2x = 3
x = 3/2 or 1.5....so ur x int is (1.5,0)
so go ahead and plot ur intercepts (1.5,0) and (0,3).....and since u have a slope of -2, start at (0,3)....come down 2 spaces, then go right 1 space....plot that...then down 2 and to the right 1...plot that...keep doing this and u should cross the x axis at (1.5,0)....then connect ur plotted points and u have ur line.
If this represents 15 percent of the total number of photos taken, which equation can be used to find the total number of photos? A. 60×4/15×4 = 240/60.
Answer:
1620°
Step-by-step explanation:
The formula for finding that measure is ...
sum of interior angles of n-sided convex polygon = 180°×(n -2)
For n=11, this is
sum = 180°×9 = 1620°
_____
Another way to get there is to remember that the sum of <em>exterior</em> angles is always 360° for a convex polygon. Then the total (interior + exterior) of the angles of an n-sided polygon is 180°×n. Subtracting the sum of exterior angles gives the total of interior angles: 180°×n -360° = 180°×(n -2).
