Answer:
12.4967 m
≈ 12.5 m
Step-by-step explanation:
From the solution diagram attached, to find /AB/, we apply sine rule:
AB/Sin 140° =AD/Sin 15°
AB = 10/Sin 15° x Sin 140°
= 24.8372 m
To calculate the height of the pole we will calculate BC first. Using the right angle triangle ∠ABC, we have:
Sin ∅ = BC/AB
Sin 25° = BC/ 24.8372
BC = 24.8372 Sin 25°
= 10.4967 m
The height of the pole = BC + 2.0
= 10.4967 + 2.0
= 12.4967
≈ 12.5 m

Discount amount= 30/100 X20
=6$
Sales tax amount =15/100X20
=3$
So total price of a shirt with discount and
Sales tax= 20$+3$_6$
=17$
So price of three shirts= 3X17
=51$
A was A for the fun of it also I’m just putting anything down cause I put no question
324/5 = (321/5)4. Now we can evaluate 321/5.. This is the fifth root of 32, which equals 2. (25 = 32) .
