This triangle is classified as a right triangle because it contains one right angle (90 degrees).
An obtuse triangle is given that classification when one of the angles is greater than 90 degrees.
An acute triangle is any triangle that has all 3 angles less than 90 degrees.
The similarities are VWX ~ YVX ~ YWV. Matching corresponding letters, you have
WX/WV = VX/VY = WV/WY
The appropriate choice is ...
B. VX/VY = WV/WY
Answer:
B
Step-by-step explanation:
The ratios are 2:1
In the table it shows 4:2, 8:x, y:6, 20:z
To find if the ratios are equivalent we would need to plug in
Once plugging in answer B we get 4:2, 8:4, 12:6, 20:10 which would all equate to 2:1
Distribute
Combine like terms
Add 1 and subtract 6x from each side
0 = 12
The equation has no real solution
Answer:
a^2 - 25.
Step-by-step explanation:
(5 + a)(-5 + a)
= -25 + 5a - 5a + a^2
= a^2 - 25.
