Step-by-step explanation:
D is the 90° angle and d=15 is opposite of the angle of the same letter. The triangle's other corners are E and F, and the sides corresponding to those angles are opposite of them too.
Angle F = 35° and E= (90-35)°= 55°. Then you could use something like the Law of Sines to find the sides if you wanted as well.
Perimeter is sum of all the sides.
SO, perimeter of that triangle will be
1/4 + 1/4 + 3/8.
The LCM of denominators (4,4,8) = 8.
Hence writing 1/4 = 2/8.
so,
Perimeter = 2/8+2/8+3/8 = (2+2+3)/8 = 7/8.
So, 7/8 ft is the perimeter of that triangle. :)
Answer:
the 4th one is the answer
Step-by-step explanation:
D. -2p + q - 5 - you have to multiply, then distribute parentheses and apply plus or minus rules.
