Answer:
Only 4 is the right answer. The rest all are false.
ANSWER
D) sin Y
EXPLANATION
The given triangle is a right triangle.
This implies that that:

Then we have

Recall that

But

When we do the substitution, we get,

Therefore cos(x) is a equivalent to sin(y).
The correct answer is D.
45x+6 is the answer
Simply
Subtract the numbers
45x-3(4-6)
45x-3(-2)
Multiply the numbers
Solution
45x+6
The product of 0.02 and 0.7 is 0.014. Notice the additional zero in the number 0.'0'2. Product is the total of two numbers multiplied or times (x).
This is the solution:
0.02
0.7
____
0.014
So the right answer is A. 0.014.
The measure of the angle FEG is probably the same as the measure of the angle FDG. There is nothing saying that EF is parallel to DG, but if so, the measure of the angle FEG is also 50º.
When the diagonals of a trapezium with two parallel bases inside of a circle are drawn, they make the same angle measure with those bases.
