Answer:
(a) ∠DAB = 59°
(b) ∠A = 135°
(c) ∠A = 99°
Step-by-step explanation:
<u>Theorem</u>: If a quadrilateral is inscribed inside a circle, then the opposite angles of the quadrilateral are SUPPLEMENTARY.
So, here in the given figures:
(1) ∠DCB + ∠DAB = 180° (as opposite angles are supplementary)
⇒∠DAB = 180° - 121° = 59°
or, ∠DAB = 59°
(2) ∠DCB + ∠DAB = 180° (as opposite angles are supplementary)
⇒(3x+6) + (x+2) = 180° or, 4x = 180 - 8 = 172
⇒ x = 172/4 = 43, or x = 43
So, ∠A = (3x+6) = 3(43) + 6 = 135°
(3) (28) + (x) = 180°
or, x = 180 - 28 = 152
So, ∠A = (x- 36) = 135 - 36 = 99°
(4)
Answer:
y < 
Step-by-step explanation:
We will find the equation of the dotted line first.
Let the equation of the line is,
y = mx + b
Here, m = slope and b = y-intercept of the line
Slope 'm' = 
m = 
m = 
Y-intercept 'b' = -3
Therefore, equation of the line is,
y =
Since, this line is a dotted line, it will represent an inequality with notation of less than or greater than (< or >)
Since, solution area (shaded area) of this inequality is below the line inequality will be,
y <
Answer:
£126
Step-by-step explanation:
Ratio is 2:1 so the difference between the amount of money will be "1". This is equal to £42 so 2 x 42 is 84 and 1 x 42 is 42, add them together and the answer is £126.
4 hours is $50, 40 hours is $500, 160 hours is $2000, 200 hours is $2500.
i’m pretty sure this is right because she makes $12.5 an hour.
