Answer:
y=4
Step-by-step explanation:
84=30y-9y, first you collect like terms.
84=21y, swap the sides
21y=84, devide both sides and you get y =4
Answer:
Hi there!
The correct answer to this question is: x=3
Step-by-step explanation:
because these two triangles are similar, that means the hypotenuse are similar. which means you can set the sides equal to each other like this:
13 = 4x + 1 minus one on both sides and you should get 4x = 12 and then divide 4 on both sides and you should finally get x = 3
H - 21 = 52
Move 21 to the other side and add it to 52
That is what H is equal to.
H = 52 + 21 = 73.
