If Angle B is two more than three times the measure of Angle C, and Angle B and Angle C are complementary angles, find each angl

dolphi86 [110]

Answer:

The measure of angle B is 68° and the measure of angle C is 22°

Step-by-step explanation:

we know that

If two angles are complementary, then their sum is equal to 90 degrees

m∠B+m∠C=90° -----> equation A

m∠B=3(m∠C)+2 ----> equation B

Substitute equation B in equation A and solve for m∠C

3(m∠C)+2+m∠C=90

4(m∠C)=90-2

4(m∠C)=88

m∠C=88/4

m∠C=22°

Find the value of m∠B

m∠B=3(22)+2=68°

therefore

The measure of angle B is 68° and the measure of angle C is 22°

$Restaurant = \{P,B\}$

$Movies = \{R,A,D\}$

$Post-movie = \{C,I\}$

Required

List out the sample space

To do this, we simply pick 1 item in each category, without repetition.

So, we have:

Minchanka [31]

Answer:

$\frac{1}{4x}$

Step-by-step explanation:

The negative exponential can be represented with the help of fractions. By this way, we also make the negative exponential disappear. For example, we can write:

$a^{-1} = \frac{1}{a}$

The explanation is this:

Since $a^{0}=1, \frac{1}{a}=\frac{a^{0} }{a^{1} } = a^{0-1} =a^{-1}$

According to this definition, we can simplify our problem in the following way:

$(4x)^{-1} = \frac{1}{(4x)^{1} } = \frac{1}{4x}$
