Because the cos theta < 0 then theta must be an obtuse angle
so a^2 + b^2 < a^2
C
So basically x and y are 4 because the hypotenuse of a 45 45 90 triangle is x square root of four. both legs of the triangle are congruent, given taht it’s a 454590
The train has 12 carriages
Step-by-step explanation:
The total no. of seats =876
No. of seats per carriage =73
It is given that each carriage has equal seats
So,
Let the total no. of carriages be x
According to the given information,
x = 12
Hence the number of carriages is 12

The United Nations has historically been the place to ask for aid and sometimes for mediation when one nation attacks another - as in Korea in 1950 or Kuwait in 1990.
Most nations in North and South America are members of the Organization of American States the OAS, which is, among other things, a mutual defense treaty to support one another in the event of attack.
I assume from your question that in this exercise you are imagining yourself to be the US President or his advisors.
Responses in a case like this would be military, using naval and air forces to support Mexican military operations, perhaps including transport of US troops to Mexico to assist. Also, bombing strategic military stations in Cuba would weaken the Cuban military's ability to support its invasion.
Given:
6 . ln x = 9.1
We are asked to find the solution of the above equation leaving the answer to two decimal places.
6lnx = 9.1
Let's divide both sides by 6
6linx/6 = 9.1/6
6 cancelling out on the left hand side.
lnx = 9.1/6
linx = 1.5166
x = e^1.5166
x = 4.5570
x = 4.56 (to two decimal places).
The correct option is A, which is x = 4.56
