d 7(13)
Step-by-step explanation:
Answer:
Explanation:
We can notice that the triangles formed are similar to the original triangle since an altitude is drawn from the right angle.
To find the measure of x, we use ratio:
Triangle 1:
Triangle 2:
So, we use the formula:
We plug in what we know:
Therefore, the answer is:
Answer:
1. Commutative Property of Multiplication
2. Commutative Property of multiplication
3. Transitive Property of equality
4. Associative Property of Addition
Step-by-step explanation:
1) (15 * 12x) * y = y * (15 * 12x) a*(b*c) = (b*c)*a
2) 22x * (3 * 4y) = 22x * (4y * 3) a*(b*c) = a*(c*b)
3) If x = 4 and 4 = y, then x = y If a=b and b=c then a=c
4) (7x + 15) + 21 = 7x + (15 + 21) (a+b) +c = a+(b+c)
