Answer:
11 feet, 26 feet, 29 feet
Step-by-step explanation:
(2x+4 middle) + (3x- 4 longest) + (x smallest )= 66
2x +3x +x +4 - 4= 6x
6x = 66
x= 66/6
x = 11
smallest = 11 feet
middle = 2(11) + 4 = 26 feet
longest = 3(11) -4 = 29 feet
Answer: B. 25.2 units
Step-by-step explanation:
The kite consists of 4 right angle triangles. The two smaller right angles are equal. Also, the two bigger right angles are equal.
To determine the hypotenuse of each triangle, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Considering the smaller triangle,
Hypotenuse² = 4² + 3² = 16 + 9 = 25
Hypotenuse = √25 = 5
Considering the smaller triangle,
Hypotenuse² = 7² + 3² = 49 + 9 = 58
Hypotenuse = √58 = 7.616
The perimeter of the kite is the sum of the length of each side. Therefore,
Perimeter = 5 + 5 + 7.616 + 7.616 = 25.2 units to the nearest tenth
Answer:
Yes it is true!
Step-by-step explanation:
2 x 5/9 equals and improper fraction of 1 1/9
It already shows that AB is 49°
in order to find ABC you must first find BC
360 - (AC + AB) = BC
360 - 156 = BC
204° = BC
NOW add BC with AB
49 + 204
253
angle ABC is 253°
now to find BAC add AB and AC
49 + 107 = 156°
angle BAC is 156°
FINALLY to find ACB add AC and CB
107 + 204
311°
angle ACB is 311°
