horsena [70]

Answer:

DOC = 70

BOC = 110

AOD = 110

Step-by-step explanation:

AOB is supplementary to BOC and AOD, which means together they equal 180. 180-70=110, so BOC and AOD are both 110.

AOB and DOC are vertical angles to each other, so are AOD and BOC. Vertical angles are always equal to each other. So since AOB is 70, so is DOC.

Hope this makes sense:)

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;

$Elsa = x + 1$

$Elsa = 56.5 + 1$

$Elsa = 57.5$
