Answer:
x = 45
Step-by-step explanation:
x = (360 - 135 * 2) / 2
x = (360 - 270) / 2
x = 90 / 2
x = 45
Answer:
y = -2/3 x + 25/3
Step-by-step explanation:
The slope = (y_2 - y_1) / (x_2 - x_1) = (9 - 7) / (-1 - 2) = -2/3.
Our equation needs to be in y = mx + b form.
We can plug in (2, 7) as our (x, y) and find b:
7 = -2/3 (2) + b
b = 7 + 4/3 = 25 / 3.
Therefore, our equation is y = -2/3 x + 25/3
Answer:
x ≈ 57.8°
Step-by-step explanation:
using the Sine rule in the triangle
= 
( cross- multiply )
8 × sinx = 11 × sin38° ( divide both sides by 8 )
sinx = 
, then
x = 
( ) ≈ 57.8° ( to 1 dec. place )
