Answer:
75°
Step-by-step explanation:
Let's find the size of x°
BCFE has four sides so the sum of its angles sizes is 360°.
● CBE + 110 + 110 + CFE = 360
CFE is equal to 65° since they have the same vertex
● CBE + 220 + 65 = 360
● CBE + 285 = 360
● CBE = 360-285
● CBE = 75
CBE and x° have the same size since they share the same vertex.so:
● x° = 75°
Answer:
CD = two square root of 10 end square root
Step-by-step explanation:
To find the length of a segment, use the distance formula. Substitute the order pairs for the endpoints of the segment. CD has the end points (-7, -4) and (-1, -2).
![d = \sqrt{(y_2-y_1)^2 + (x_2-x_1)^2} \\\\d = \sqrt{(-4--2)^2 + (-7--1)^2} \\\\d = \sqrt{-2^2 + -6^2}\\\\d = \sqrt{4 + 36}\\\\d=\sqrt {40} = 2\sqrt{10}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28y_2-y_1%29%5E2%20%2B%20%28x_2-x_1%29%5E2%7D%20%5C%5C%5C%5Cd%20%3D%20%5Csqrt%7B%28-4--2%29%5E2%20%2B%20%28-7--1%29%5E2%7D%20%5C%5C%5C%5Cd%20%3D%20%5Csqrt%7B-2%5E2%20%2B%20-6%5E2%7D%5C%5C%5C%5Cd%20%3D%20%5Csqrt%7B4%20%2B%2036%7D%5C%5C%5C%5Cd%3D%5Csqrt%20%7B40%7D%20%3D%202%5Csqrt%7B10%7D)
She would make 3.00 dollars
50(10) - 20(10) = (10)(50 - 20)
500 - 200 = (10 * 30)
300 = 300
(10)(50 - 20) = 30(10)
(10 * 30) = 300
300 = 300
