3z-4=6z-17
-3z-4=-17 (subtracted the 6z from both sides)
-3z=-13 (added the 4 to both sides)
z=
(divided both sides by -3z)
z=
Answer:
the two angles are 55° each
Step-by-step explanation:
Let the two equal angles be y each
Therefore,
70° + y + y = 180°
Collect like terms
2y = 180 — 70
2y = 110
Divide both side by the coefficient of y i.e 2
y = 110/2
y = 55°
Therefore, the two angles are 55° each
Answer:
The one on the bottom right
Step-by-step explanation:
Answer: These might be some properties :
The angle in a semicircle is a right angle.
Angles in the same segment are equal.
Opposite angles in a cyclic quadrilateral sum to 180°
Step-by-step explanation:
Answer: 126
Step-by-step explanation: this is the distributive property so you multiply the number outside the parentheses times the numbers inside the parentheses
