Answer:
Isosceles triangles have two sides with the same length, and one side that ... Similarly, if two angles of a triangle have equal measure, then the sides ... (2) Set up an equation and solve for x. ... x = 60/2 x = 30. Each base angle of triangle ABC measures 30 degrees. ... In isosceles triangle RST, angle S is the vertex angle.
Step-by-step explanation:
Answer:
Step-by-step explanation:
Multiply both sides of the equation by 5.
5 · · 5 · 4
Simplify both sides of the equation.
Subtract 10 from both sides of the equation.
Divide each term by 2 and simplify.

Substitute x for 6
Multiply 3 · 6
Add 18 + 9
Divide ÷ 27
9 = 9
48/4= 12 pens per box
12*9 = 108 pens in 9 boxes
