Answer:
∠W = 73°
∠Y = 26°
∠X = 81°
Step-by-step explanation:
∠W + ∠X + ∠Y = 180°
∠W = 3x - 5
∠X = 3x - 5 + 8
∠Y = x
3x - 5 + 3x - 5 + 8 + x = 180
7x = 182
x = 182 / 7 = 26
Answer:
ED: 6.5 cm BE = 14.4 cm
Step-by-step explanation:
Add 20 and 5 to get side AC.
25/20 gives us the scale factor to go from 25 triangle ABE to triangle ACD.
Multiply 26 by the SF to get AD.
Subtract length of AD by AE to get ED. You should get 6.5 cm (don't forget units!!!!)
To go from triangle ACD to triangle ABE, we can do 20/25 to get the scale factor.
Using that number, multiply it with 18 to get BE.
The answer should be 14.4 cm.
This is possible because the two triangles ACD and ABE are similar via the angle angle angle similarity theorem depicted in my screenshot.
Answer:
A and B are correct
Step-by-step explanation:
The middle letter represents the vertex of an angle. For instance, angle ABC has a vertex at B. Because the letter "e" is in the middle of angle FED and angle DEF, it represents the vertex of those angles. Hope this helps
Answer:
27 you take from the lowest then highest and then add the two left over together and divide by two for their mean.
Use the quadratic formula to get x = (3 - 2*sqrt(6))/3 or x = (3 + 2*sqrt(6))/3
