-88 is the answer to that
X = 2y + 8
x - y = 25
2y + 8 - y = 25
y = 25 - 8
y = 17
x = 2y + 8
x = 2(17) + 8
x = 34 + 8
x = 42
the larger number (x) = 42...and the smaller number (y) = 17
Answer:
(a) PT = 13 cm
(b) <PTR =
Step-by-step explanation:
(a) Applying the Pythagoras theorem to QST, we have;
= +
= +
= 36 + 64
100
QS =
= 10
QS = 10 cm
Since QS = TR, then;
WT = TR
= x 10
WT = 5 cm
Thus, applying Pathagoras theorem to PWT;
= +
= +
= 144 + 25
= 169
PT =
= 13
PT = 13 cm
(b) To determine <PTR, TR = 10 cm. Apply the required trigonometric function;
Cos θ =
Cos θ =
= 0.7692
θ = 0.7692
= 39.7179
θ =
Therefore, <PTR =
Answer
A
Correct me if I’m wrong
The solution to the problem is as follows:
Since:
Perimeter = 2L + 2W
L = <span> 3x-1
W = </span><span> 3x-3
Perimeter = 2(3x-1) + 2(3x-3) = 6x-2+6x-6 = 12x-8
Therefore, the answer would be 12x-8.
I hope my answer has come to your help. God bless and have a nice day ahead!
