You do $\frac{sin(y)}{2} = \frac{sin30}{what you got for x}$ and then cross multiply and simply it.

$(what you got for x)sin(y)=2sin30$
divide (what you got for x) to both side
you should get something like $sin(y)= \frac{2sin30}{what you got for x}$
then just use a calculator and do $sin^{-1} ( \frac{2sin30}{what you got for x} )$

The common point between lines y = 2x + 5 and y = ½ x + 6 is (3, 1/2). true or false

mixer [17]

The common point between y = 2x + 5 and y = (1/2)x + 6 will have the same values for x and y.

Therefore, set the two y expressions equal to obtain
2x + 5 = (1/2)x + 6

Subtract (1/2)x from each side.
(3/2)x + 5 = 6

Subtract 5 from each side.
(3/2)x = 1

Multiply each side by 2/3.
x = 2/3.

From the first equation, obtain
y = 2*(2/3) + 5 = 19/3.

The common point is (2/3, 19/3). It is not equal to (3, 1/2).

a bank offers a home improvement loan with simple interest at an annual rate of 12% j.t. borrows $14000 over a period of 3 years

I am Lyosha [343]

Interest = PRT/100
I= 14000*0.12*3
I=5040

Add Interest to the Principal
14000 + 5040
= $19,040
A is the answer.

For a two column proof, we want to start with the given information. From there, we will use various definitions, postulates, and theorems to fill in the rest.

Our two sets of given information are that Plane M bisects Line AB and that Line PA is congruent to Line PB.

We know from the definition of a bisector that it splits a line in two equal parts. Therefore, Line AO must be congruent to Line BO.

Now, we have two sides of a triangle that we have proved to be congruent to each other. From the image given in the original problem, we see that both triangles share Line OP. Line OP is congruent to Line OP through the reflexive property.

We now have proven that all three sides of the one triangle are congruent to the corresponding sides on the other triangle. Therefore, the triangles are congruent through the SSS theorem.
