A. (Number of sides - 2) x 100, so
6-2= 4 x 180
= 720° is the sum of all angles in a hexagon
84 + 87 + 128 + 150 + 103 = 552
720 - 552 = 168
X = 168°

2. Angles in a triangle sum up to 180°
36 + 57= 93
180 - 93 = 87
A= 87°

Enter the number in standard notation.
Jobisdone [24]
<h3>The length in standard notation is 0.05 meter</h3>

<em><u>Solution:</u></em>

Given that,

Jeremy measured the length of an ant as 5 \times 10^{-2}\ meter

We have to write the length in standard notation

From given,

Length = 5 \times 10^{-2}\\\\Length = \frac{5}{10^{2}}\\\\Simplify\\\\Length = \frac{5}{100}\\\\Length = 0.05

Thus the length in standard notation is 0.05 meter

<em><u>Method 2:</u></em>

length = 5 \times 10^{-2}\ meter

Use the exponent of 10 to determine how many places to move the decimal point

Since exponent is -2, is negative

Thus, we have to move the decimal point to right 2 places

5 \times 10^{-2} = 0.05

Thus the length in standard notation is 0.05 meter

Please help asap!! finding value
notsponge [240]
Hey there :)

The given are 104, 137, 154, 131 and we have to find x
The mean value is 130

Mean = sum of all values divided by total number of values
130 = \frac{104+137+154+131+x}{5}

130 x 5 = 526 + x

650 = 526 + x

124 = x


Your answer will be option A) 124
