Answer: 34 degrees
Step-by-step explanation:
The starting temperature was -5 degrees at 5am, and after two hours, the temperature was 34 degrees at 7am. The temperature increased by 39 degrees, how did we get this answer?
You add -5 and 39
-5 + 39 = 34
A tip for adding negatives:
When you get a problem similar to -5 + 39, you can actually flip them around if you need an easier understanding. So it would be 39 - 5. Both equations still equal 34 as long as you keep the values of each number!
Answer:
15 ft
Basic fact:
<em>a square is a quadrilateral shape that has all sides of the same length and all the angles are the same</em>
Step-by-step explanation:
using the fact above, we know that there are 4 sides of the same length
to find the length of one side we have to do
60/4
=15
Answer:
x = 65 , y = 64
Step-by-step explanation:
y - 16 and 2y + 4 are same- side interior angles and sum to 180° , that is
y - 16 + 2y + 4 = 180
3y - 12 = 180 ( add 12 to both sides )
3y = 192 ( divide both sides by 3 )
y = 64
then
2y + 4 = 2(64) + 4 = 128 + 4 = 132
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
2y + 4 is an exterior angle of the triangle , then
x + 67 = 132 ( subtract 67 from both sides )
x = 65
