XYA = (104 -52)/2
52 /2 = 26
the answer is 26 degrees
Answer:
To find a range of values for the third side when given two lengths, write two inequalities: one inequality that assumes the larger value given is the longest side in the triangle and one inequality that assumes that the third side is the longest side in the triangle. Combine the two inequalities for the final answer.

Answer:
6 months
Step-by-step explanation:
12x = 87
12x ÷ 12 = x
87 - 15 = 72
72 ÷ 12 = 6
x = 6 months
CHECK:
12 x 6 = 72 + 15 = 87
87 = 87
Answer:
(5, - 8 ) and (- 1, 4 )
Step-by-step explanation:
Given the 2 equations
y = - x² + 2x + 7 → (1)
y = - 2x + 2 → (2)
Substitute y = - 2x + 2 into (1)
- 2x + 2 = - x² + 2x + 7 ← subtract - x² + 2x + 7 from both sides
x² - 4x - 5 = 0 ← in standard form
(x - 5)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x + 1 = 0 ⇒ x = - 1
Substitute these values into (2) for corresponding values of y
x = 5 → y = - 2(5) + 2 = - 10 + 2 = - 8 ⇒ (5, - 8)
x = - 1 → y = - 2(- 1) + 2 = 2 + 2 = 4 ⇒ (- 1, 4)
Answer:-4×8=-36 -4+8=4
Step-by-step explanation:
you cant get 5 its impossible unless you do some crazy wizardry stuff but you do -4×8 witch equals -36 then you do -4+8 witch equals 4 hope I did this correctly >^<
