Answer: From the figure attached,
Point X is the midpoint of line AC.
Since coordinates of the midpoint of the segment joining endpoints and is given by,
Therefore, coordinates of the point X will be, = (a, a)
From triangle AXB,
Length of AB = 2a
Length of AX =
Length of BX =
=
Length of AX = BX =
Therefore, triangle AXB is an isosceles triangle.
Step-by-step explanation:
X=20 distribute and combine like terms then divide
Answer:
y = 5
Step-by-step explanation:
Since this is an isosceles triangle, Angle B and Angle C are equivalent. We can use this to find x
3x = 75
x = 25
Angles in a triangle add up to 180, so knowing the measure of Angle B and Angle C, we can find the measure of Angle A
Angle A = 180-(75+75)
Angle A = 180-150
Angle A = 30
We know Angle A = 4y+10
4y + 10 = 30
4y = 20
y = 5
Answer:
143ft
Step-by-step explanation:
12in is 1 foot and 13x11 (11x13) is 143
Answer:
D
Step-by-step explanation:
Given
x³ + 2x² + 7x + 14 ( factor the first/second and third/fourth terms )
= x²(x + 2) + 7(x + 2) ← factor out (x + 2) from each term
= (x² + 7)(x + 2) → D
