Answer: The measure of angle CAE = 120°.

Step-by-step explanation:

Since we have given that

In a circle a, m∠CFE = 240°

We need to find the angle i.e.m∠ CAE .

As we know the theorem, that the measure of its intercepted arc is double the measure of an inscribed angle.

Here, in our case, the measure of an inscribed angle is m∠CFE = 240°.

So, the measure of its intercepted arc i.e. m∠ CAE  is given by

\frac{1}{2}\times 240^\circ\\\\=120^\circ

Hence, the measure of angle CAE = 120°.

Show a reciprocal numerical expression for each equation using multiplication, please!

\frac{2}{3}÷ 4 = \frac{2}{3} \times  \frac{1}{4} = \frac{1}{6}

\frac{1}{8}÷ 3 = \frac{1}{8} \times \frac{1}{3} = \frac{1}{24}

\frac{3}{4}÷ 6 = \frac{3}{4} \times \frac{1}{6} = \frac{1}{8}

\frac{1}{36}÷ 2 = \frac{1}{6} \times \frac{1}{2} = \frac{1}{12}

The value of the exponent in (22)−5<br><br>is​
lyudmila [28]

Answer:

Let's calculate:

22-5

• Remove minus in the exponent and invert the base:

= (1/22)5

• Expand the multiplication:

= (1/22) * (1/22) * (1/22) * (1/22) * (1/22)

• Find your result:

= 1/5153632 ≈ 0.000000194038
