Answer:

see explaination

Step-by-step explanation:

length (l) = 2x+7

width (b) = 9x

area of rectangle = l×b

=(2x+7)(9x)

=18x^2+63x

perimeter of rectangle = 2(l+b)

=2(2x+7)(9x)

=2(18x^2+63x)

=36x^2+126x

Find m∠U.<br> Write your answer as an integer or as a decimal rounded to the nearest tenth.
Ilia_Sergeevich [38]

Answer:

∠U = 56.4

Step-by-step explanation:

We can use trigonometric functions to solve this

Here we are given the opposite side of ∠U as well as the adjacent side.

When dealing with the adjacent and opposite side we use sin

Sin = Opposite side / Adjacent side

Opp = 5 and adj = 6

So

Sin(U) = 5/6

* take the inverse sine of both sides *

arc(sin)(u) = u

arcsin(5/6) = 56.4 *( rounded to the nearest tenth )

∠U = 56.4
