Answer:
The perimeter of △DEF 43
Step-by-step explanation:
Sin A/ a = Sin B / b = Sin C/ c
sin D/ d =
Sin E / e = sin F /f
sin 52/ e = sin 90 / 18
e = 18 x sin 52 / sin 90
e = 14.184 /1
e = 14.2
From phythagoras theorem ,
/hyp/² = /opp/² + /adj/²
18² = 14.2² + /adj/²
/adj/²= 18² - 14.2²
/adj/² = 324 + 201.64
/adj/² = 119.51
/adj/ = √122.36
= 11.1
Perimeter of Triangle = a + b +c
where a = side
b = base
c = side
Perimeter = 18 + 11.1 + 14.2
Perimeter = 43.3
Perimeter= 43
Perimeter is 34.5 area is 62
Hello there!
4³ + 2(3 - 2)
= 64 + 2(1)
= 64 + 2
= 66
The correct answer is option C
The second part*
A variable cubed >>>>> x³
Quotient of some number and three >>> b ÷ 3
Product of an unknown value and three >>>>> 3a
Three less than a variable >>>y - 3
Three more than some number >>>> z + 3
