Answer:
see explanation
Step-by-step explanation:
The opposite angles of an inscribed quadrilateral are supplementary, thus
5x + 20 + 7x - 8 = 180
12x + 12 = 180 ( subtract 12 from both sides )
12x = 168 ( divide both sides by 12 )
x = 14
Thus
∠ RQP = 10x = 10(14) = 140°
∠PSR = 180° - 140° = 40° ( opposite angles are supplementary )
∠ SRQ = 7X - 8 = 7(14) - 8 = 98 - 8 = 90°
∠ QPS = 5x + 20 = 5(14) + 20 = 70 + 20 = 90°
Answer:
A) y = -2x
B) y = x - 3
Step-by-step explanation:
A) you need to have a negative 'x' coefficient and no y-intercept
B) you need to have a positive 'x' coefficient and a negative y-intercept
Answer: 24cm
Step-by-step explanation:
R = 25 cm
S = 7 cm
T = ?
The square of equals to the addition of the square of S and the square of T.
R^2 = S^2 + T^2
25^2 = 7^2 + T^2
T^2 = 25^2 - 7^2
T^2 = 625 - 49
T =✓576
T = 24cm

Answer:
-3
Step-by-step explanation:
Note that when you multiply two negative numbers, the answer will result as a positive number. Also note that when you multiply a negative number with a positive number, then your answer will result in a negative number.
(-1)(-1) = 1
(1)(-3) = -3
-3 is your answer.
