Answer:
(1, 3)
Step-by-step explanation:
Given coordinates of 2 endpoints, G(-2, 5) and H(4, 1), midpoint of AB is calculated as shown below:
Midpoint (M) of GH, for G(-2, 5) and H(4, 1) is given as:
Let
Thus:
Coordinates of the midpoint of GH = (1, 3).
AC = 18
BC = 6x
AB = 2x + 4
Write and solve:
18 + 6x + 2x + 4
18 + 8x + 4 = 180
You can solve further:
18 + 8x = 176
8x = 158
x = 19 & 3/4
Not 100% sure what the question is asking, but hopefully this helps.
Answer:
D.
Step-by-step explanation:
Find the angles in both isosceles triangles.
Let's start with RXWGC first, they mentioned R was 96°, an isosceles triangle also is an triangle which two of the angles in the triangle are the same and one is different.
180 - 96 = 84° (The degree of two other angles)
84 ÷ 2 = 42° (The degree of each angle of the two same angles which is W and C)
After that, find the angles of the other isosceles triangle which is ELWG.
As mentioned that E is 40°, do the same as what was done in RXWGC.
180 - 40 = 140° (The degree of two other angles)
140 ÷ 2 = 70° - (The degree of each angle of the two same angles which is W and C)
Since you have found the degree for X and G...
180 - 42 - 70 = 68° (Degree of X in the small isosceles triangle)
$20 - $14.98 = $5.02
- You must subtract 20 from 14.98
