Hello,
3^x+1=15
==>3^x=14
==>x*ln(3)=ln(14)
==>x=ln(14)/ln(3)
==>x=2,40217350273....
The first one because angle one is the same degrees as angle 8, which proves why p is parallel to q
Solution:
<u>Note that:</u>
- Percentage formula: x/100 × y = x% of y
<u>Use the formula to solve 20% of 180.</u>
- x/100 × y = x% of y
- => 20/100 × 180
- => 1/5 × 180
- => 36
20% of 180 is <u>36.</u>
