Find x and y from the triangle.

Mathematics
1 answer:
lidiya [134]3 years ago
7 0

Answer:

x = 39

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180° , then

x + x + 12 + 90 = 180

2x + 102 = 180 ( subtract 102 from both sides )

2x = 78 ( divide both sides by 2 )

x = 39

Then

x = 39°

x + 12 = 39 + 12 = 51°

adam walk 2 miles a day for the first week of his exercise plan. the he walk 3 miles a day for the next 9 days. how many miles d
Digiron [165]

Answer:

41 miles

Step-by-step explanation:

The first week, which is 7 days, Adam walked 2 miles a day. So, we have the multiplication equation: 2 * 7 = 14 miles.

For the next 9 days, Adam walked 3 miles per day. So, we have the multiplication equation: 3 * 9 = 27 miles.

Now, we just add these two values together:

14 + 27 = 41 miles

Thus, the answer is 41 miles.

Hope this helps!
