we can divide the composite shape into on quadrilateral and triangle as shown in the diagram. since the line that joins the two shape is parallel to the base AB, the angle DEC is 85°.The angle CEA is 180°- angle DEC = 180-85=95. Angle BCE is sum of angle CEA, ABC and EAB subtracted from360°= 360°-(95+95+85)=85°. Angle DCE is 120°- ECB=35°. So, angle CDE = 180°-(35°+85°)= 60°. For reference see the diagram.
ANSWER
1. Multiply the fraction by 5/5 to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
EXPLANATION
Renaldo wants to write
as a decimal.
He needs a denominator of 100, so he can multiply by
to obtain:
This will be
He can now obtain the decimal equivalent as
The correct choice is option 1.
Let's solve your equation step-by-step.
Step 1: Add 5 to both sides.
Step 2: Solve Exponent to get.
