Answer:
< 2 and < 3 are complementary
Step-by-step explanation:
< 2 and < 3 are complementary because since 1 and 2 are complementary and 1 is congruent to 3 that would mean that 1 and 3 are equal degrees, so you could replace one with 2 as shown here: < 1 and < 2 are complementary and < 1 is congruent to < 3, then < 2 and < 3 are complementary. Assume < 1, < 2, and < 3 do not equal 45 degrees.

K is the constant in a table or equation. like k=x•y
Answer:
15 y 8
Step-by-step explanation:
y = x - 7
x² + y² = 289
sustituir: x² + (x - 7)² = 289
distribuir: x² + x² - 14x + 49 = 289
sustraer + simplificar: 2x² - 14x - 240 = 0
dividir: x² - 7x - 120 = 0
x² - 15x + 8x - 120 = 0
(x - 15)(x + 8) = 0
x = 15, x = -8 --> x ≠ -8 porque -8 no es naturales
sustituir: y = 15 - 7
simplificar: y = 8
Step-by-step explanation:
1. Use the Pythagorean theorem to solve for side KM:
- 16^2+KM^2=34^2
- 256+KM^2=1156
- KM^2=900
- KM=30
2. Cosine is adjacent over hypotenuse, so cosine of M would be KM/34, or 30/34
3. Tangent is opposite over adjacent, so tangent of L will be KM/16, or 30/16
4. Sine is opposite over hypotenuse, so sine of M will be 16/34
5. KM=30, solved for in step 1.
hope this helps!!
