Question

The folding chair has different settings that change the angles formed by its parts. Suppose m<2 is 31 and m<3 is 72. Find m<1 using the diagram.

Answer 1

first find out the angle of the triangle inside 2 and 3

Answer 2

A- 123
B-113
C- 93
D- 103

Answer 3

@GirlByte I don't know how to do that...

Answer 4

Just look how many degrees in 2 and 3

Answer 5

It is an acute angle because it has less than 90 degrees

Answer 6

Now find the value of the angle.

Answer 7

@GirlByte but none of the answers are less than 90?

Answer 8

Um it's only a solution not the answer it self

Answer 9

The answer is 103 btw.

Answer 10

Now to get this answer you need to follow me -.-

Answer 11

@GirlByte THen will you please help me get to the answer because I am very confused...

Answer 12

Sure

Answer 13

Ok First off we need to find the value of the angle 2 3

Answer 14

which is 31 and 72

Answer 15

add those and subtract from 180 since a triangle has 180 degrees

Answer 16

@GirlByte 77

Answer 17

since angle 1 and this angle we found out rite now are supplementary angles we can just subtract 77 from 180 and find the angle of 1

Answer 18

Yes correct. but we are trying the find the answer of <1 right?

Answer 19

yes

Answer 20

and the answer is 103 ^_^
