Answer:
90
Step-by-step explanation:
the colums add up to angle 1, which make angle 2 adjacent.
9-9=0
Answer: 
Step-by-step explanation:
By definition, an Isosceles triangle has two equal sides and its opposite angles are congruent.
Observe the figure attached, where the isosceles triangle is divided into two equal right triangles.
So, in this case you need to use the following Trigonometric Identity:

In this case, you can identify that:

Substituting values, and solving for "x", you get:

Therefore, the length of BC rounded to nearest tenth, is:

Answer: 5.150
Step-by-step explanation:
1. Multiply 28 by 6/7
2. Multiply 21 by 2/9
3. Divide 24 by 4.66
Answer:
effective annual rate is 6.16 %
Step-by-step explanation:
given data
rate = 6 % = 0.06
time 5 year = 10 semi annually
to find out
effective annual rate
solution
we know formula for annual effective rate of interest is
rate of interest =
-1
put here all value
rate of interest =
-1
rate of interest =
-1
rate of interest = 0.061646
so effective annual rate is 6.16 %
I'm not sure about the second image.
But the first one is telling you to translate x, 3 units left, and translate y, 4 units up.
(-6, 0) will turn to (-9, 4)
I subtracted 3 from -6 and added 4 to 0.
