Find the value of x in each triangle. ( pls i need this is a test grade)

answer:

i think x is 70

step-by-step explanation:

a straight line is 180. therefore the side with no x is 40 and when you add the 3 inner sides of a triangle it also has to be 180.

therefore the 40+x+x=180

the x's are the same value because its iscoceles

so 2x=140

x=70

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
