The first one is 4 x 10^-9
second one is 4 x 10^10
third one is 5 x 10^7
fourth on is 2 x 10^-5
37.5 + 37.5 = 75 ; also, 37.5 x 2 = 75
9 5/7 because 7 goes into 68, 9 times and you have a remainder of 5
Answer:
Step-by-step explanation:

The value of
.

The value of
is 150°. ✅

We know that,

➡ 81° +
= 180°
➡
= 180° -81°
➡
= 99°
Since an exterior angle of a triangle is equal to the sum of the two opposite interior angles, we have
=
+ 51°
Substituting the value of ''
" in the above equation,
➪
= 99° + 51°
➪
= 150°
