1. A triangle has side lenghts of 9, 9 and 12. Is there triangle right, obtuse, or acute 2. Find the third side of a right triangle has a leg measuring 8 cm and hypotense measuring 15 cm.

A. 161 cm
B. 17 cm
C. 12,7 cm
D. 289 cm

What does each angle measure in a regular 20-gon?

360 degrees
180 degrees
162 degrees
3,240 degrees

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

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)
