Question

I NEED HELP PLEASEEEEE ASAPPPPPPP

Answer 1

7x+40=180

Explanation:

(5x+40)+(2x)=180

7x+40=180

if you were to solve

subtract 40 from each side

7x=140

divide both sides by 7

x=20

check your answer

5(20)+40+2(20)=180

100+40+40=180

this is correct

hope this helps..and with future questions if you need to solve it

To find BCD

we know that C is 40 degrees and we know that triangle is also 180

we can also see that B is a right triangle or 90 degree

so 90+40+A=180

130+A=180

subtract 130 from 180

A=50
