A right triangle does have perpendicular line because they can cross if the lines go on forever
A quadilateral is a 4 sided shape so if you talking about the square or a rectangle or a parralelogram no it does not have perpendicular sides BUT if you are talking about a trapezoid it does have pependicular side
HOPE THIS HELPS!!!!!!! ;-)
PLZ MARK ME AS BRAINLIEST!!!
Answer:
A y-intercept is the point on a graph where the line crosses the y-axis. For example, a y-intercept of 5 would mean that the line crosses the y-axis at the coordinates (0, 5).
An x-intercept is then pretty self explanatory. It is the point on a graph where the line crosses the x-axis. For example, an x-intercept of 3 would mean that the line crosses the x-axis at the coordinates (3,0).
Hope this helps you understand! :)
Answer:
c = 28.26 cm
Step-by-step explanation:
equation for circumference of a circle is 2πr
r = d/2 so here r = 9/2 = 4.5
2 x 3.14 x 4.5 = 28.26
Answer:
29°
Step-by-step explanation:
cos x = 84/98
x = cos-1(84/98)
x = 28.9
