Answer:14/20 and 10/12
Step-by-step explanation:
7/10
Multiply both numerator and denominator by 2
7/10=(7×2)/(10×2)=14/20
5/6
Multiply both numerator and denominator by 2
5/6=(5×2)/(6×2)=10/12

Answer: ≈ 5.2
Step-by-step explanation:
You're gonna want to use the Law of Cosines to solve:
c² = a² + b² -2abcos(R)
c² = 6² + 9² - 2(6)(9)cos(34°)
c² = 36 + 81 - 108cos(34°)
c² = 117 - 108(.82904)
c² = 27.46368
√c² = √27.46368 => 5.2405 = 5.2
Answer:
The length of the longest side is 68mm
Step-by-step explanation:
The perimeter of a triangle is equals to the sum of all its sides
P=a+b+c
The triangle is isosceles, so two of its sides are equal, have the same length.
So: a=b, then
P=2a+c=168mm
Moreover, we know that the base is 18mm more than each of the legs, this means: c=18mm+a, where we obtain that a=c-18mm.
So, the system of equations is solved, lets use the above result in Perimeter`s equation.
168mm=2*(c-18mm)+C
From here we have:
168mm=3c-36mm
We obtain the following result: c= 68mm, this the length of the longest side
