Answer:
∠ QRS = 43°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
4n - 9 + 5n - 18 + 90 = 180, that is
9n + 63 = 180 ( subtract 63 from both sides )
9n = 117 ( divide both sides by 9 )
n = 13
Thus
∠ QRS = 4n - 9 = 4(13) - 9 = 52 - 9 = 43°
∠ RSQ = 4n - 18 = 4(13) - 18 = 65 - 18 = 47°
Radical 2 = 1.4 So 1.4 * 6 = 8.4
a^2 + b^2 = c^2
8.4^2 + 8.4^2 = square root of c
70.56 + 70.56 = 141.12 ≈ 141
Then you must find the square root of 141 which is 11.874 ≈ 11.9
Side a = 8.4
Side b = 8.4
Side c = 11.9
Answer:
$210
Step-by-step explanation:
Formula:
P = A (1 + r% x t)
P: Answer
A: Original value
R%: Percentage increase
T: Time
P = 200 (1 + 5% x 1)
P = $210
