Given:
ABCD is a cyclic quadrilateral.
m∠C = 43°
To find:
The measure of ∠A.
Solution:
<em>In cylic quadrilateral, opposite angles are supplementary.</em>
⇒ m∠A + m∠C = 180°
⇒ m∠A + 43° = 180°
Subtract 43° from both sides.
⇒ m∠A + 43° - 43° = 180° - 43°
⇒ m∠A = 137°
The measure of ∠A is 137°.
The answer is 348.00. You have to multiply 7.25 by 24 and then use the product and double it.
W - the width
l - the length
P = 6984
P = 2w + 2l
l = 3w
substitute
2w + 2 · 3w = 6984
2w + 6w = 6984
8w = 6984 |:8
w = 873
l = 3 · 873 = 2619
Answer: the length = 2619 and the width = 873
