slated surface
17 × 20 = 340
2 triangle sides
2 × 8 × 15 ÷ 2 = 120
backside
8 × 20 = 160
bottom
15 × 20 = 300
sum all of it
340 + 120 + 160 + 300 = 920

Answer: C & E
40% is equal to 0.4 as a decimal. As a fraction it is equal to 2/5 in simplest form.
In order to find the present you would have to multiple one of the numbers above by the initial value 84.
If you would like further explanation let me know. :)
Cos y = 16 / 17.89 = 0.8944
y = cos^-1 (0.8944) = 26.57°
tan 26.57 = BA / 17.89
BA = 17.89 tan 26.57 = 8.95
tan x = 17.89 / 8.95 = 1.999
x = arctan 1.999 = 63.43
sin x = sin 63.43 = 0.8944
Answer:
Basic proportionality therom states: If a line is drawn parallel to one side of a triangle intersecting other two sides, then it divides the two sides in the same ratio.
Step-by-step explanation:
Hey there! :D
Plug in the solution.
5(2) + 2(-3)=4 || 10-6=4 || 4=4 <== true
4(2) + -3= 11 || 8-3= 11 || 5=11 <== not true
4. is not a solution.
3(1)+2(5)=13 || 3+10=13 || 13=13 <== true
4(1)-3(5)=-11 || 4-15=-11 || -11=-11 <== true
5. is a solution
2(-6) - 5(-2)=-22 || -12+10=-22 -2=-22 <=== not true
6. is not a solution
I hope this helps!
