we all know that the total of degrees is 180 so 70+70=140
180-140=40
so the answer is 40

we have a figure with 4 angle so the total of degrees is 360 so the answer is 126

the answer most be 50 becuse we have a Special degree witch always equal 90 if we have recatngle so
x+40=90
X=50 the answer and if you want to try again choose the second one
2x-10=90
2x=100
X=50 same answe you see
