How is 1 and 23/100 expressed as a decimal
AleksandrR [38]
1 is expressed in decimal simply as 1.00
23/100 is expressed in decimal by 0.23

1 is a whole number and for it to become a decimal we must convert it into a fraction and perform division. 1 in fraction form is simply 1/1 which equals to 1.

23/100 to become decimal we need to divide 23 by 100. It will give us a quotient of 0.23

Use the Exterior Angle Theorem to find the measure of each angle.
navik [9.2K]

Answer:

∠ C = 36°

∠ D= 81°

∠ DEC= 63°

Step-by-step explanation:

<em>The exterior angle of a triangle is equal to the sum of the interior opposite angles. </em>

<em />

∴   (11y + 4) + (5y + 1) = 117

         11y + 4 + 5y + 1 = 117

         16y + 5 = 117

         16y = 117-5

         16y = 112

         y = 112÷16

         y = 7

∠ C = 5×(7) + 1 = 36°

∠ D = 11×(7) + 4 = 81°

∠ DEC = 180- 117 = 63°
