Answer:

You prove the base angles are congruent by constructing the angle bisector through the vertex angle of an isosceles triangle. By constructing the angle bisector, we designed two congruent triangles and then used CPCTC to show that the base angles are congruent.

A yogurt shop offers 6 different flavors of frozen yogurt and 12 different toppings. How many choices are possible for a single

Goryan [66]

Answer:

#3) 72; #4) 40,320; #5) 90.

Step-by-step explanation:

#3) The number of possible choices are found by multiplying the choices of flavors and the choices of toppings:

6*12=72.

#4) The ordering of 8 cards is a permutation, given by 8!=40,320.

#5) This is a permutation of 10 objects taken 2 at a time:

P(10,2) = 10!/(10-2)!=10!/8!=90.

P.S I had the same question once.

What is the measure of A?

BabaBlast [244]

Answer:

Step-by-step explanation:

Since the sides are equal, the angles have to be equal

The angles of a triangle add to 180

180/3 = 60

Angle A = 60

The top of a 230 foot vertical tower is to be anchored by cables that make an angle with a measure of 50 degrees with the ground

Triss [41]

Answer:

cable length: 300.2 ft
anchor distance: 193.0 ft

Step-by-step explanation:

The side given is opposite the given angle. We want to find both the hypotenuse and the adjacent side in the right triangle that models the geometry.

Sin = Opposite/Hypotenuse

sin(50°) = (230 ft)/h

h = (230 ft)/sin(50°) ≈ 300.24 ft

The length of the cable must be about 300.2 feet.

Tan = Opposite/Adjacent

tan(50°) = (230 ft)/d

d = (230 ft)/tan(50°) ≈ 192.99 ft

The cable must be anchored about 193.0 ft from the tower.
