The formula for the area of a triangle is a= bh over 2. use this to complete parts a-b

a. solve this formula for h

b. use this new formula to find the value of h if a = 54 in (squared) and b= 12 in

0if x and y vary inversely and y=6 as x=7, what is the constant of variation?

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m

Solve 2 - 3 cos x = 5 + 3 cos x for 0° ≤ x ≤ 180° a. 150° b. 30° c. 60° d. 120°
