One leg of a right triangle has a slope of -4. What is the slope of the other leg?

Si la base de un triángulo isósceles mide 70 m y el ángulo opuesto a ésta mide 58°; entonces ¿cuánto mide la altura de dicho triángulo? a) 21.87 m. b) 40.01 m. c) 43.74 m. d) 63.14 m.

Does anyone know how to solve and graph this: 4 + | a + 2 | < 7the only part i don't get is the "4 +"

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
