Answer:
Perimeter = 120 inches
Area = 176 inches 2
Step-by-step explanation:
For perimeter, all you have to do is add. For area, you would normally have to multiply, but since the numbers are all squared, all you have to do is add them
Answer:
0A + B = 3AB
10 / B = 3 - (1/A)
10/B is between 2 and 3.
B = 5, A = 1
Step-by-step explanation:
you just need to do this but i dont know
The rule for multiplying similar bases with exponents:
(a^b)(a^c)=a^(b+c)
In this case we have:
(5^-2)(5^-1)
5^(-2-1)
5^(-3)
The rule for negative exponents:
a^(-b)=1/(a^b)
So in this case:
5^(-3) is equal to
1/(5^3)
1/125

Answer:
see explanation
Step-by-step explanation:
Using the cosine and tangent ratios in the right triangle
cos41° =
=
= 
Multiply both sides by VX
VX × cos41° = 7 ( divide both sides by cos41° )
VX =
≈ 9.3
-----------------------------------------------------------------------
tan41° =
=
= 
Multiply both sides by 7
7 × tan41° = WX, thus
WX ≈ 6.1
-------------------------------------------------------------------------
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180° for ∠ X
∠ X = 180° - (90 + 41)° = 180° - 131° = 49°
