Answer:
B
Step-by-step explanation:
sinA=opp/hyp
sinA=16/20=4/5
cosA=adj/hyp
cosA=12/20=3/5

<u>(-2)+2=0, (-0.5)+0.5=0, and (-5)+5=0</u>
All those equations answers are 0, please mark me brainiest, and hope I helped!
4x + 3y = 12
3y = -4x + 12
y = -4/3x + 4........so the slope (or gradient) is -4/3...because in y = mx + b form, the slope(gradient) is in the m position and the y int is in the b position....so if u wanted to know the y axis, it would be (0,4)
the x intercept (where the line crosses the x axis) can be found by subbing in 0 for y in the original equation or the slope intercept equation, and solving for x.
4x + 3(0) = 12
4x = 12
x = 12/4 = 3....so the x intercept is (3,0)
