For these problems you have to use PEMDAS so for problem 15 you would do the parentheses first, (21-3) you get 18 and then exponents, 3^2, you get 9, no multiplication but there is division so take your answers, 18 and 9 and divide them, you get 2, so the answer to 15 is 2.

Hey, there!!
As it is a parallelogram, remember basic properties of parallelogram,
- Their opposite sides are parallel and equal to eachother.
- Their opposite angles are equal.
- They have properties of parallel lines too.
Now, lets solve your question.
b = (7×10)°
Therefore, b= 70°.
now, (3x+10°)+b=180° { co- interior angle of a triangle sum is 180°}.
or, 3x= 180°-80°
or, x= 100°/3
Therefore, x= 33° { rounding off we get 33}.
w+ b =180°
w+70°=180° { coointerior angles are equal}.
Therefore, w =110°
