i am not sure about this but yeah also can i have brainliest
Answer:
x = 45.6°
Step-by-step explanation:
As we can see, this is a right triangle, so there are known relationships
well to start we have to know the relationship between angles, legs and the hypotenuse
α = x°
a: adjacent
o: opposite = 5
h: hypotenuse = 7
sin α = o/h
cos α = a/h
tan α = o/a
we see that it has (angle, hypotenuse, opposite)
is the sine
sin α = o/h
sin x = 5/7
x = sin^-1 (5/7)
x = 45.58°
if we want to round to the nearest tenth
x = 45.58° = 45.6°
Answer:
x=-4
Step-by-step explanation:
Distribute and expand everything in brackets.
2x+2*4x+2*-2+3x=x+3*x+3*-8+4x
2x+8x-4+3x=x+3x-24+4x
Solve like terms
13x-4=8x-24
Place like terms on same side.
13x-8x=-24+4
Solve for x
5x=-20
x=-4
