Answer:
The measures of the angles are 65° and 80°
Step-by-step explanation:
One of the angles is 35°
We know that the other two angles have a difference of 15°
With this knowledge we can write an equation.
2x symbolizes the two angles
+15 symbolizes the difference between the two angles
145 = 2x + 15
145 - 15 = 130
2x = 130
x = 65
65 is the size of one of the angles.
Next, we add 15 to 65 and we get 80
80 is our second angle

14x + -21xy
Factor out the Greatest Common Factor (GCF), '7x'.
7x(2 + -3y)
Final result:
7x(2 + -3y)

Step-by-step explanation:
i think
To answer this question you will use the
Pythagorean Theorem. a^2+b^2=c^2. In this
case a and b are the same because it is a
square. So 2x^2=1600 (c^2 where c=40).
Solve this equation ( divide both sides by two
and find the square root for both). Each side
length should be approximately 28.3 cm.
