Answer:
<DEB= 125 degrees
Step-by-step explanation:
To get this, you would need to know all 2 angles of the triangle.
To find the first angle, simply do 180-107 to get 73(because supplementary angles add up to 180 degrees).
Next, 180-52(given angle)-73 to get 55 because the 3 angles of a triangle add up to 180(triangle angle sum theory).
You would see that <DEB is part of another supplementary angle so, do 180-55 to get 125.
<DEB=125 degrees.
The first one, 4x is the slope and the +3 is the y-intercept

Answer:
20
Step-by-step explanation:
using the given formula:
V = 1/3(Base Area)(height)
V = 1/3 (5)(12)
V = 1/3 (60)
V = 20
<h3><u>

:</h3>
x = 50.5°
<h3><u>
Explanation</u>
:</h3>
In order to solve, get to know about the sine rule:
<h3><u>Solve for BD</u>:</h3>
Then find angle D = 180° - 78° = 102°
<h3><u>Solve for angle C</u></h3>
<h3><u>Total Sum of interior angles of a triangle is 180</u>°</h3>
