The range is the highest number minus the lowest number
98 - 13 = 85 <==
your answer would be 147°
solution:
since ∠x and ∠y are supplementary angles. they must add up to 180°
so ∠+∠y=180°
∠x=180°-∠y
= 180°- 33°
=147
Log_10 100 is the same as 10 to the x power is 100
10^x=100
10^2=100
the answer is 2
Let the no. be x
A/Q
=> 36 × x /100 = 18
=> x = 18 × 100 / 36
=> x = 50
