Answer:
angle 2 = 90° {corresponding angles}
angle 7 + angle 5 = 180° {linear pair}
or, angle 7 + 100° = 180° {angle 5 is corresponding to 100°}
so, angle 7 = 80°
Taking a sqrt=taking a 1/2 power, so when you take a power of a power, you multiply them. So you’re finding 10.3^(3/2).

Step-by-step explanation:
log 3 (10022)
= 8.38561
log n (155)= 8.38561
n^8.38561=155
log 10 (n)= log 10 (155)
lpg 10 (155)= 2.190331698
8.38561 log10 (n)=2.190331698
log10 n = 2.190331698÷8.38561
lo^-1 (0.2612012)
=1.825
n=1.825
