Answer:

x is $60^o$

Step-by-step explanation:

Notice that angle 'x" is opposed via the vertex to the angle obtained by subtracting 150 degrees from 90 degrees (right angle), and therefore should be of the same measure.

Then:

$x=150^o-90^o=60^o$

Answer:

see below

Step-by-step explanation:

We can see the blue angle is 150° and is made up of 90° and something. That something is 150 - 90 = 60°. Since x and 60° are vertical angles, x = 60°.

Answer:

$\displaystyle E=26log2-24log3+8log 5$

Step-by-step explanation:

Logarithms

There are certain properties of the logarithms we'll need to recall in order to simplify the expression given in the question. We'll list them below

$log(x.y)=logx+logy\\log(x/y)=logx-logy\\logx^y=y.logx$

We'll also need to factor the following numbers into their prime factors:

$20=2^2\cdot 5$

$16=2^4$

$15=3\cdot 5$

$25=5^2$

$24=2^3\cdot 3$

$81=3^4$

$80=2^4\cdot 5$

The original expression is

$\displaystyle E=log20+16log\frac{16}{15}+12log\frac{25}{24}+log\frac{81}{80}$

Plugging in the factored values

$\displaystyle E=log(2^2\cdot 5)+16log\frac{2^4}{3\cdot 5}+12log\frac{5^2}{2^3\cdot 3}+log\frac{3^4}{2^4\cdot 5}$

Applying the properties we have

$\displaystyle E=log2^2+log 5+16(log2^4-log3-log 5)+12(log5^2-log2^3-log 3)+log3^4-log2^4-log 5$

$\displaystyle E=2log2+log 5+16log2^4-16log3-16log 5+12log5^2-12log2^3-12log 3+log3^4-log2^4-log 5$

$\displaystyle E=2log2+log 5+64log2-16log3-16log 5+24log5-36log2-12log 3+4log3-4log2-log 5$

Simplifying

$\boxed{\displaystyle E=26log2-24log3+8log 5}$

Find the area of the shaded portion in the square. (assuming the central point of the arc is the corresponding corner)

-Dominant- [34]

To find the area of the shaded piece, subtract the square area to the area of the sector.
