Answer:
Option A. 52°
Step-by-step explanation:
From the figure attached,
JEFH is a parallelogram and ΔFGH is a scalene right triangle.
If m∠JEF = 142°
m∠JHF = 142° [Since opposite angles of the parallelogram are equal]
m∠FHG + m∠JHF = 180°
m∠FHG + 142° = 180°
m∠FHG = 180 - 142
= 38°
In the given scalene right triangle FGH,
m∠FHG + m∠HFG + m∠HGF = 180°
38° + m∠HFG + 90° = 180°
m∠HFG = 180° - 128°
m∠HFG = 52°
Option A. will be the answer.
The given, the proposition , the statement column, the reason column, and the diagram if one is given.
728 because you multiply all the number
Answer:
a = sqrt(c^2 - b^2)
see image.
Step-by-step explanation:
If you square both sides of the equation, you get the Pythagorean Theorem back again.
c = sqrt(a^2 + b^2)
c^2 = a^2 + b^2
Solve for a means to get a all by itself on one side of the equation. Subtract b^2 and then take the square root. See image.
Step-by-step explanation:
(x-3)(x^2+2x+1)
=x^3-3x^2+2x^2-6x+x-3
=x^3+2x^2-3x^2-6x+x-3
=x^3-x^2-5x-3
