Please help with this equation!

Mathematics
1 answer:
ASHA 777 [7]4 years ago
5 0

Answer:

15,75,90

Step-by-step explanation:

the 2 acute angles of a right triangle add to 90 degrees

the other angle is a right angle which equals 90 degrees

lets call them x and y

x = 5y  one is 5 times the other

x+y = 90

substitute x=5y

5y+y =90

combine like terms

6y =90

divide each side by 6

y = 90/6

y = 15

x = 5*y

x = 5*15

x = 75

the three angles are x, y, right angle

75, 15, 90

put them in order from smallest to largest

15,75,90

What is the length of the hypotenuse of the triangle? Triangle A B C. Side A C is 8 centimeters and side C B is 15 centimeters.
klio [65]

Answer:

The hypotenuse is 17

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

8^2 + 15^2 = c^2

64 + 225 = c^2

289 = c^2

Take the square root of each side

sqrt(289) = sqrt(c^2)

17 = c
