What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 73° and its congruent sides each measure 15 cm?

The measure of the vertex angle will be 34°

Step-by-step explanation:

As isosceles triangle have two equals sides and two equals angle. The two equals angle are the base angles b. We know that the sum of the angle of a triangle is 180°:

v+b+b=180°

v+2b=180°

Where v is the vertex angle. If we know the value of the base angles is 73° then the remaing vertex angle will be calculated by solving for a in the equation above:

v=180°-2*73°

v=180°-146°=34°

answer: check all that apply, where the options?

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
