Answer:
X = 12
Step-by-step explanation:
Right angles = 90°
90° - 42° = 48°
48° ÷ 4 = 12°
1.5 hours just subtract the two numbers
Answer:
A'(7, - 3 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
A(- 7, 3 ) → (- 7, - 3 )
Under a reflection in the y- axis
a point (x, y ) → (- x, y ), thus
(- 7, - 3 ) → A'(7, - 3 )
Rewrite 4x^2-3x+9=2x+1 as 4x^2-5x+8 = 0
Here, a = 4, b = -5 and c = 8. Then,
5 plus or minus sqrt (25 -4(4)(8) )
x = ------------------------------------------------------
8
5 plus or minus sqrt (-103)
= --------------------------------------
8
5 plus or minus i*sqrt(103)
Then x = ----------------------------------------
8
= ---------------------------------------------
8
= ----------------------------
You started off very well. You identified the given and the pair of congruent sides.
Statement Reason
3. m<POM = m<NMO Alternate Interior Angles
4. m<NOM = m<PMO Alternate Interior Angles
5. ΔPMO ≅ ΔNOM ASA
6. MP ≅ NO CPCTC
Reasoning for statement 3: This is because MN ║PO and MO acts as a transversal.
Reasoning for statement 4: This is because MP ║NO and MO acts as a transversal.
