Answer:
Step-by-step explanation:
Yes they are congruent because they are the same sized shape
Answer:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
Step-by-step explanation:
yeah
Answer:
x = 5
Step-by-step explanation:
Given
x = ( square both sides )
x² = 3x + 10 ( subtract 3x + 10 from both sides )
x² - 3x - 10 = 0 ← in standard form
(x - 5)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x + 2 = 0 ⇒ x = - 2
As a check
Substitute these values into the equation and if both sides are equal then they are solutions.
x = 5
right side = = = 5 = left side ← solution
x = - 2
right side = = = 2 ≠ - 2 ← not a solution
Thus x = 5 is the solution to the equation
It's convex if it has internal angles over 180 degrees, or if they're pointing inwards. Using that, 3 and 6 both clearly have angles pointing inwards, why 4 and 5 don't
Answer:
D. 180 ÷ 3 = m
Step-by-step explanation:
The sum of the angles in a triangle adds up to 180°.
Since equilateral triangles have 3 equal angles,
sum of the angles in the triangle= 3m
3m=180°
m= 180° ÷3
m=60°
Thus, 180÷3=m
