The ages Edna, and Elsa are consecutive integers. The sum of their ages is 114. What are their ages?

OLEGan [10]

Answer:

Edna = 56.5

Elsa = 57.5

Step-by-step explanation:

Represent Edna age with x; Elsa age will be x + 1

So,

$x + x + 1 = 114$

$2x + 1 = 114$

Make 2x the subject

$2x = 114 - 1$

$2x = 113$

Solve for x

$x = 113/2$

$x = 56.5$

Elsa age is calculated as thus;

$Elsa = x + 1$

$Elsa = 56.5 + 1$

$Elsa = 57.5$

How do you answer this

Tju [1.3M]

109 degrees and the missing angle are supplementary angles, so they add up to 180 degrees.
180 - 109 = 71
The measurement of ULE can now be found since we now have 2 angles with their degrees. So we add those angles together...
71 + 49 = 120
Now we subtract that from 180 (all of the angles add up to 180 in a triangle) to get the m180 - 120 = 60

The m
