Question

In the accompanying, figure ABCD is a rhombus and measure of angle CAB = 42. Find the measure of angle ABC.
I'll draw the diagram.

Answer 1

Is it 48 or 42? or something else?

Answer 2

It cannot be 48 or 42 because angle ABC is an acute angle (<90). This angle is obtuse. So you need to find the obtuse angle measurement which is >90.

Answer 3

so is it 138?

Answer 4

It can be. Do you have the options?

Answer 5

no..

Answer 6

I can't give you the precise measurement, but since this is an obtuse angle and 138 is greater than 90.

Answer 7

Oh okay
