Answer:
x=5 and 3
Step-by-step explanation:
x^2-8x+21=6
x^2-8x+21+16=6+16
(x-4)^2=1
(x-4)=±1, x=5 and 3
Answer:
cos=24/25
tan=7/24
Step-by-step explanation:
sin=opposite/hypotenuse
therefore 7 is the opposite and 25 is the hypotenuse.
using pythagorean theorem we can find the adjacent. i.e hypotenuse squared= sum of adjacent squared and opposite squared.
h^2= a^2+ O^2
25 squared - 7 squared= 576
which is equal to 24 squared.
therefore adjacent=24
cos=adjacent/hypotenuse
cos=24/25
tan=opposite/adjacent
tan=7/24.
4 loads of stone ... 2/3 ton
1 load of stone ... x ton = ?
If you would like to know the weight of 1 load of stone, you can calculate this using the following steps:
4 * x = 2/3 * 1
4 * x = 2/3 /4
x = 2/3 / 4
x = 2/12 = 1/6 ton
The correct result would be 1/6 ton.
