Answer: y=−1 or y=2
Step-by-step explanation:
Answer:
≈ 23.4
Step-by-step explanation:
A = bh
270 = 15b
b = 18
Now you know the two legs, use the Pythagorean Theorem to find the value of the hypotenuse: a² + b² = c²
15² + 18² = c²
225 + 324 = c²
c² = 549
c = √549
Answer:

Step-by-step explanation:
Use the inverse cosine function.



Answer:
69 is your answer
Step-by-step explanation:
Have a wonderful day and good luck on you're test!
Answer:
a = 28 / √2
Step-by-step explanation:
Isosceles triangle therefor a = b
use pythagorean theorem
a² + a² = c²
2a² = 28²
a² = 28² / 2
Take the square root of both sides
a = 28 / √2
