Answer:
14
14
47
Step-by-step explanation:
An isosceles triangle has two opposite sides. If the two angles are equal , it means the triangle is an isosceles. Because 90 degrees is greater than 45 degrees, the two sides with the same length, would have a smaller length than the third side.
5 + 3x + x + x = 75
5 + 5x = 75
5x = 70
x = 14
5 + 3(14) = 47
Answer:
5 is their common denominator
Step-by-step explanation:
A common denominator is when both denominators are the same.
Answer:
A. Area is 15cm x 15cm = 225cm is the area of 1 tile.
B. She will need 484 tiles
C. She will need to purchase 14 boxes
Step-by-step explanation:
Answer:
Just substitute the values in!
(-5/9) + (-4/3) - 2/3 = - 5/9 - 12/9 - 6/9 = -23/9.
Yes. You did it right. Most of the angles are corresponding, and once you found the measure of x, you could use the corresponding angles postulate.
