Hint: The sum of the interior angles of a triangle is 180 degrees.
(The general formula (n-2)*180.) Do the calculations to find the missing angle of triangle.
In quiestions with quotation marks (monomials and polynomials)
You treat this problem as though it's a regular triangle.
You plug the numbers 24 and 45 into the equation for a triangle which is A=1/2 (L x W)
So what you get is A= 1/2 (24 x 45)
Which can be simplified to A= 12 x 45.
In the end that totals to 540 meters.
Answer:
MO = 12
PR = 3
Step-by-step explanation:
The perimeter of a triangle is calculated by adding all side lengths up:
The perimeter of triangle MNO is given as 48
The perimeter of triangle PQR is given as 12
The ratio is 1/4 (simplified ratio of 12/48)
we can write the following equation using this information:
cross multiply fractions
12x = 4x + 8
subtract 4x from both sides
8x = 8
divide both sides by 8
x = 1
Now to find the measure of side lengths in question we replace x with 1
for MO = 12x
12*1 = 12
for PR = x + 2
1 + 2 = 3
