Answer:
24 cm
Step-by-step explanation:
The triangle must have the ratio of 6:7:9 for side lengths. If the triangle had these exact sides then the perimeter would be 6 + 7 + 9 = 22 cm. Since the triangle has 88 cm as its perimeter then 22*4 = 88. This means multiplying by a scale factor of 4 will give the side length.
6 * 4 = 24
7* 4 = 28
9 * 4 = 36
The perimeter is 24 + 28 + 36 = 88 cm.
The shortest side is 24.
Answer: 40
Step-by-step explanation: It is going up by a constant of 9, so 31 + 9 = 40.
<u>Answer:</u>
<h2>
ST = 44.54 ft</h2>
<u>Explanation:</u>
given:
∠T=90° , ∠R=39° and TR = 55 ft
ST = 55×tan(39)
ST = 55×0.80..
ST = 44.54 ft
6n+n n=5
substitute
6(5)+(5)
30+5
35
