Answer:
∠ BAC = 80°
Step-by-step explanation:
The sum of the interior angles of quadrilateral ACDB = 360°
DB and DC are tangents to the circle, thus
∠ DBA = ∠ ACD = 90° ( angle between tangent/ circle at point of contact )
Thus
∠ BAC + 90° + 90° + 100° = 360°
∠ BAC + 280° = 360° ( subtract 280° from both sides )
∠ BAC = 80°

Answer:
v = - 5
Step-by-step explanation:
Given
- 18 = 5v + 7 ( subtract 7 from both sides )
- 25 = 5v ( divide both sides by 5 )
- 5 = v
Answer:
Y and Z because just move the shape side ways and u can find the corresponding side.
Answer:
x=0
Step-by-step explanation:
-8x + 2(4x + 2) = 4
Use distributive property to get rid of the parentheses
-8x + 8x + 4 = 4
Add the like terms.
x + 4 = 4
Subtract both sides by four.
x = 0
