Answer:
a=90⁰
b=40⁰
c=140
d=40⁰
Step-by-step explanation:
<em><u>Main</u></em><em><u> </u></em><em><u>princip</u></em><em><u>le</u></em>
Achieve 180⁰ on every line
<em><u>a </u></em><em><u> </u></em> was achieved by virtue of the 90⁰ symbol
b = a+ 50⁰(90⁰+50⁰-180)
c=a+50⁰(vertically opposite angle) if you need some help,a=90⁰ (already explained above).
d=b(vertically opposite angle)
just so you understand the concept especially that of vertically opposite angles (b is vertically opposite d and therefore are equal so no calculations needed there, in the case of c, two angles when put together are opposite c so they have to be summed up and the sum is equal to angle <em>c</em>.
Think of it as an infinity loop the two angles facing each other are the same
<em><u>OR</u></em>
like the "x" symbol every angle is equal to angle direct opposite to it.
<em><u>Note</u></em><em><u>:</u></em> Don't get confused with opposite and adjacent.
444 divided by 3 equals 148
