The 2 interior angles add to the exterior angle
26+13=x
39=x
x=39°
because
remember, all angles add to 180
26+13+BCA=180
39+BCA=180
minus 39 both sides
BCA=141
look, we want x
BC is a striaign line which is 180
BCA+x=180
141+x=180
minus 141 from both sides
x=39°

Answer:
Base of rectangle = 23.25 units (Approx.)
Step-by-step explanation:
Given:
Diagonal of rectangle (Hypotenuse) = 8x
Height of rectangle (Perpendicular) = 2x
Find:
Base of rectangle
Computation:
Base = √Hypotenuse² - Perpendicular²
Base of rectangle = √(8x)² - (2x)²
Base of rectangle = √64x² - 4x²
Base of rectangle = √60x²
Base of rectangle = 7.75x units (Approx.)
If x = 3
Base of rectangle = 7.75x
Base of rectangle = 7.75(3)
Base of rectangle = 23.25 units (Approx.)
Answer:
see explanation
Step-by-step explanation:
1
Given
2x² - 16 = 0 ( add 16 to both sides )
2x² = 16 ( divide both sides by 2 )
x² = 8 ( take the square root of both sides )
x = ± 
= ± 2
------------------------------------
2
Given
- 5x² + 9 = 0 ( subtract 9 from both sides )
- 5x² = - 9 ( divide both sides by - 5 )
x² = 
( take the square root of both sides )
x = ± 
= ± 
-----------------------------------------
3
Given
6x² - 15 = 27 ( add 15 to both sides )
6x² = 42 ( divide both sides by 6 )
x² = 7 ( take the square root of both sides )
x = ±
