Find the area of the triangle with the given measurements. round the solution to the nearest hundredth if necessary. b = 67°, a = 10 cm, c = 20 cm 92.05 cm2 184.1 cm2 100 cm2 39.07 cm2

Among many other formulas, the area of a triangle is

where B is the angle between sides a and c.

92.05 sq cm, first choice

Bonus. Here's a formula for the area S of a triangle your teacher doesn't know:

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)

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake
