Question

Find the value of x in each case.

Answer 1

x= 80 in CDE

and x=32.75 in CBA

Explanation:

we know that all the angles of a triangle =180

so you subtract 180 form 100 and u get 80

and on the next one you set up 4x+49=180 subtract 49 on both sides and u get 131 and then u divide 4 on both sides and u get 32.75 you can check your work
