answer:

<em>∠F = 74°</em>

explanation:

<u>( Find the value of x  )</u>

<u></u>

<em>∠</em> E + <em>∠</em> F = 180°

9x - 38 + 2x + 42 = 180

11x + 4 = 180

11x = 176

x = 16

<u>( Find </u><u><em>∠</em></u><u> F using x )</u>

<em />

<em>∠ </em>F = 2x + 42

x = 16

<em>∠</em> F = 2(16) + 42

<em>∠ </em>F = 32 + 42

<em />

<em>∠F = 74°</em>

What is -0.8 as a fraction?
stira [4]

Answer:

-\frac{4}{5}

Step-by-step explanation:

There is not much that can be done to figure out how to write 0.8 as a fraction, except to literally use what the decimal portion of your number, the .8, means.

Since there are 1 digits in 8, the very last digit is the "10th" decimal place.

So we can just say that .8 is the same as 8/10.

The fraction is not reduced to lowest terms. We can reduce this fraction to lowest  terms by dividing both the numerator and denominator by 2.

Why divide by 2? 2 is the Greatest Common Divisor (GCD)  or Greatest Common Factor (GCF) of the numbers 8 and 10.

So, this fraction reduced to lowest terms is  4/5

So your final answer is: 0.8 can be written as the fraction 8/10 simplified to 4/5

Radius = 110 mm
110² = 10,000 mm² = Area

Radius = 15 mm
15² = 225 mm² = Area

Hope this helps!
