Answer:
the longest side of the first triangle is 32 cm
Step-by-step explanation:
Given;
dimension of the smaller triangle = 4.5cm 6cm and 8 cm.
the longest side of this smaller triangle = 8 cm
Perimeter of the first triangle = 74 cm
let the increase in dimension of the similar first triangle = x
the longest side of the first triangle = 8x
4.5x + 6x + 8x = 74
18.5x = 74
x = 74/18.5
x = 4
the longest side of the first triangle = 8 x 4 = 32 cm
Answer:
7π/6
Step-by-step explanation:
The way to convert radian to degree is to convert π to 180 degrees. We know that π radian is equal to 180 degrees and therefore.
A) 7(180)/6 = 7(30) = 210 degrees
B) 6(180)/7 = 1080/7 = approx 154.2 degrees
C) 7(180)/3 = 7(60) = 420 degrees
D) 3(180)/7 = 540/7 = approx 77.1 degrees
When we convert π rad to 180 degrees and evaluate, we will get the rad value in degree form.
Therefore, 7π/6 = 210 degrees. Hence, A is the answer.
Answer:
A
Step-by-step explanation:
Area of a triangle = 
where b = base length and h = height
the triangle shown has a base length of 2 and 1/2 and a height 4. and 2/5
So area =
5.5 also = 
Hence, the correct answer is A
