Mark is making a decoration for a rally, using a string of triangular strips. each strip is an isosceles triangle when flattened out. what is the measure of the third angle? a) 35° b) 40° c) 45° d) 50°

The measure of third angle is 40°

B is correct.

Step-by-step explanation:

Mark is making a decoration for a rally, using a string of triangular strips. Each strip is an isosceles triangle when flattened out.

In figure, we are given the base angle is 70°

For isosceles triangle base angles are equal.

Two angle of a isosceles triangle are 70° and 70°

Let third angle of triangular strips be A

Using angle sum property of triangle ( sum of all three angles of a triangle is 180°)

A+70°+70°=180°

A=180-140 = 40°

Hence, The measure of third angle is 40°

step-by-step explanation:

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
