One angle in a triangle is 100 degrees. the other two angles are congruent. what is the measure of one of the missing angles?
(a) 40°
(b) 80°
(c) 130°
(d) 140°

A

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

let x be the measure of the congruent angles, then

x + x + 100 = 180, that is

2x + 100 = 180 ( subtract 100 from both sides )

2x = 80 ( divide both sides by 2 )

x = 40

Thus the measure of one of the congruent angles is 40°

answer: i believe its b. if you sound out the sentences that sounds wrong.

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 ! ~
