Question

The second angle in a triangle is 3/4 as large as the first one. the third in a triangle is 2/3 as large as the second angle. find the angle measure and draw a possible figure

Answer 1

can someone help me!!!!!

Answer 2

its okay

Answer 3

form the smallest, let the sides of the triangle is a, b, c.
according information above, we have :

a = a
b = 3/4 a
c = 2/3 b = 2/3 (3/4 a) = 1/2 a

we knowed that sum of them equals 180, so
a + b + c = 180

now subtitute b and c (in a), get
a + b + c = 180
a + 3/4 a + 1/2 a = 180

solve for a, first

Answer 4

okay then

Answer 5

a + 3/4 a + 1/2 a = 180
solve for a, first

after that, subtitute the value of a into the equations of b and c above

Answer 6

okay thank u very much
