Angles B and D are congruent so:

(360-112-74)/2=87°

The measure of the angle is A, 87.

The total of all the angles have to add up to 360 and we know that the 2 missing angles have to be the same because the congruent lines.

112+74=186. 360-186=174/2=87

Hope this helps and have a great day! :D

Ryann planned on swimming 14 miles. Instead, he was only able to swim 1/4 of that distance. How many miles did Ryan swim?

mote1985 [20]

Hey there,

Given the question it shows that Ryann swam 1/4 of 14 miles that he was supposed to swim.

In words of is another way to say 1/4 * 14...

14/4

This expressed as a mixed number would be...

3 and 2/4 or 3 1/2

Of the 14 miles that Ryann was supposed to swim he swam 3 1/2 miles.

Hope I helped,

Amna
