Find the perimeter of oqr if oq=6.5. a. 6.1 b. 12.2 c. 13 d. 19.1

ANSWER

The correct answer is 19.1

EXPLANATION

The perimeter of triangle OQR is the sum of the distance around the triangle.

Thus,

We can observe that two of the angles are equal.

The angles that are equal measures 62° each.

Therefore triangle OQR is an isosceles triangle. This means that

Hence,

units.

D. 19.1

Step-by-step explanation:

We know the length of the two sides: OQ = 6.5 and RQ = 6.1.

Since two of the angles in the triangle are same, it is an isosceles triangle.

So the sides that opposite the same angle are of equal length, therefore the side OR is also 6.5.

Now that we know the lengths of all three sides, we can add them up to find the perimeter of this triangle.

Perimeter of OQR = 6.1 + 6.5 + 6.5 = 19.1

Therefore, option D, 19.1 is the correct answer.

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
