Answer:
28 degrees
Step-by-step explanation:
Because a triangle equals 180, you can subtract 90 and 34 from triangle ABE to leave you with 56 degrees for angle B.
Since CBA is a straigth line with 180 degrees, you can subtract 56 to end up with 124 degrees for angle CBE.
Since line BD bisects angle EBC (splits in half), you can divide the 124 degrees into 62 degrees.
Now that we know angle CBE equals 62 degrees, we can add the 90 degrees and subtract them from the 180 degrees of the triangle.
62+90=152
180-152=28
Answer:
21.75
Step-by-step explanation:
Plugging in the variables, you'd get 24 - (20-4) over (4 + 4). Add the contents of the parenthesis and you'd get 24 - (18)/(8). You'd divide, and get 24- 2.25, or 21.75.
If you aren't supposed to simplify on this assignment, it would probably be 24 - 18/8, or if you use fractions 21 and 3/4.

Step-by-step explanation:
Given
x - 2.6 = 1.8
x = 1.8 + 2.6
x = 4.4

Answer:
A = 10.5%
B = 28.9%
C = 39.5%
D = 18.4%
F = 2.6%
Step-by-step explanation:
Add all the frequencies together = 38
- 4/38 × 100 = 10.5%
- 11/38 × 100 = 28.9%
- 15/38 × 100 = 39.5%
- 7/38 × 100 = 18.4%
- 1/38 × 100 = 2.6%
10.5 + 28.9 + 39.5 + 18.4 + 2.6 = 100%
